Image Formatting MS Paint allows you to format any picture that you want. Some changes that you can make include the following (Figure 5.9): • Cropping the picture to only show the selected item • Resizing an object • Rotating the object Cropping lets you change the picture so only the selected part is visible. STEP1: On the Home tab, in the Image group, click the arrow under Select, and then click the kind of selection you want to make. STEP 2: Drag the pointer to select the part of the picture you want to show. In the Image group, click Crop. STEP 3: To save the cropped picture as a new file click the Paint button, point to Save as, and then click the file type for the current picture. STEP 4: In the File name box, type a new file name, and then click Save. We can resize an image by using the Resize option. If you want to tilt the image vertically or horizontally, you can use the Skew option (under the Resize option). Rotate Option lets you change the angle of the picture to certain preset degrees, i.e., 90 and 180 degree angles.

6 EDITING TEXT IN MS WORD Hey, Friends! We learnt some of the basic features of Word 2007. Let’s quickly revise them and know some more about WORD. Let Us Start MS Word is a very popular word processing software. We can open, save and close a document in MS Word. We also can enter text in Text Area and make changes in that text using different features in MS Word. Let Us Do 1: Type the names of any five animals in a new Word doc. Now, save this with the name ‘Animals’. Can you write the steps here? STEP 1: __________________________________________________________ STEP 2: __________________________________________________________ STEP 3: __________________________________________________________ STEP 4: __________________________________________________________ STEP 5: __________________________________________________________ In this lesson The basics of working with text, including how to insert, delete, select, copy, cut, paste, and drag and drop text. 52 15-12-2017 12:06:40 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 58

Basic Editing Tasks Editing is one of the important features of MS Word. It allows us to make changes to a document. To edit any text we need to select the text. We can also insert or delete text, undo or redo the changes. It also allows us to search and replace text. Here, we will discuss various editing features. To Insert Text STEP 1: Move your mouse to the location where you want the text to appear in the Text area. STEP 2: Click the mouse. The Insertion point (Fig. 6.1) Fig. 6.1 appears. Type the text you want.  Place the insertion point next to the text you want to delete. STEP 2: Press the Backspace key on your keyboard to delete text to the left of the insertion point. STEP 3: Press the Delete key on your keyboard to delete text to the right of the insertion point. To Select Text Text can be selected partially or wholly by using either the mouse or the keyboard. Using the Mouse • To select a word, double-click on it. • To select a sentence hold down the Ctrl key and click anywhere in the sentence. • To select a paragraph, triple-click anywhere in the paragraph or double click in the left margin of the paragraph. • To select a desired portion of text STEP 1: Place the insertion point next to the text you want to select. STEP 2: Click the mouse. While holding it down, drag your mouse over the text to select it. JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 59 53 15-12-2017 12:06:40

STEP 3: Release the mouse button. You have selected the text. A highlighted box will appear over the selected text. (Fig. 6.2) Fig. 6.2 When you select text or images in Word, a Hover toolbar (Fig. 6.3) with formatting options appears. This makes formatting commands easily accessible, which can save you time. If the toolbar does not appear at first, try moving the mouse over the selection. Fig. 6.3 Hover Toolbar Using the Keyboard Selection Keyboard Shortcut Whole text in the doc Ctrl + A Text on the right side of the cursor Shift + Right Arrow Text on the left side of the cursor Shift + Left Arrow Text on the left side and above the cursor Shift + Up Arrow Text on the right side and below the cursor Shift + Down Arrow Text from beginning of the line till the cursor Shift + Home Text from the cursor till the end of the line Shift + End 54 15-12-2017 12:06:40 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 60

Cut, Copy and Paste Text Let us now learn how to cut, copy and paste text in the document. In MS Word, the same sentence or word can be used many times, without typing it again and again. For this reason, the cut, copy and paste tools come handy. To copy and paste text Fig. 6.4 STEP 1: Select the text you want to copy. Fig. 6.5 STEP 2: Click the Copy command on the Home tab. You can also right-click your Document and select Copy. (Fig. 6.4) STEP 3:  Place your insertion point where you want the text to appear. STEP 4:  Click the Paste command on the Home tab. The text will appear. To cut and paste text: STEP 1: Select the text you want to move. STEP 2: Click the Cut command on the Home tab. You can also right-click the document and select Cut (Fig.6.6). STEP 3: Place your insertion point where you want the text to appear. STEP 4:  Click the Paste (Fig. 6.5) command on the Home tab. The text will appear. Fig. 6.6 You can also cut, copy, and paste by right-clicking the document and choosing the desired action from the drop-down menu. When you use this method to paste, you can choose from three options that determine how the text will be formatted: Keep Source Formatting, Merge Formatting, and Keep Text Only (Fig. 6.7). You can, however, bring the cursor over each icon to see what it will look like before clicking it. JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 61 55 15-12-2017 12:06:40

To Drag and Drop Text Fig. 6.7 STEP 1: Select the text you want to copy (Fig. 6.8). STEP 2: Click and drag the text to the location where you want it to appear. The cursor will have a rectangle under it to indicate that you are moving text. Fig. 6.8 STEP 3: Release the mouse button, and the text will appear. Do You Know? If text does not appear in the exact location you want, you can click the Enter key on your keyboard to move the text to a new line. Find and Replace Text When you’re working with longer documents, it can be difficult and time-consuming to locate a specific word or phrase. Word can automatically search your document using the Find feature, and it even allows you to change words or phrases using Replace. To Find Text STEP 1: From the Home tab, click the Find command (Fig. 6.9). The Navigation pane will appear on the left side of the screen. 56 15-12-2017 12:06:40 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 62

Let Us Start You can put a bullet or number against the text to make the list more attractive. Several bulleting and numbering styles are available. You can select the one you wish to use. In the previous class, we learnt the different tools and features of MS Word. Now, we will learn more about formatting features in MS Word application. Let us recall what we have learned in the previous classes before we know about more tools. Let Us Do 1: Identify and write the commands or options for the given shortcut keys. Ctrl + L Ctrl + Y Ctrl + R Ctrl + J Ctrl + U Ctrl + U Ctrl + Z Ctrl + B Ctrl + X Ctrl + C Ctrl + E Ctrl + V JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 69 63 15-12-2017 12:06:41

Formatting means making a document attractive and presentable. MS Word provides various formatting features. Let us discuss how to use these features. In this lesson We will learn Different ways to format text. Create bulleted or numbered list. How to check spelling and grammar and change case of the text. Bullets and Numbering We can display data in the form of points using the Bullets and Numbering feature of MS Word. We can select the one we wish to use. Do You Know? By default, MS Word 2007 uses a simple black dot as the bullet. There are several bulleting and numbering styles available. Steps to create lists with bullets are as follows: STEP 1: Type the text you want to add bullets to. STEP 2: Select the text you typed. STEP 3: Click on the Home tab. STEP 4: In the Paragraph group, click the down arrow next to the Bullets button. The Bullet Library appears. STEP 5: Click to select the type of bullet you want to use. Word adds bullets to your list. 64 15-12-2017 12:06:41 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 70

STEP 3:In the Paragraph group, click the down arrow next to the Bullets/Numbering icons. A dialog box appears. STEP 4: Click None. Word removes the bullets/numbers from the list. Spelling & Grammar Have you ever noticed the red and green wavy underlines while typing a letter? These are the spelling and grammatical mistakes in the document. By default, Word checks the spelling and grammar of any written document. Words typed in the document are compared to the ones that are available in the dictionary file. Any word that is not present in the dictionary is marked as incorrect. These spellings and grammar are indicated by coloured wavy lines.(Fig. 7.3) • Red line indicates a misspelt word. • Green line indicates a grammatical error. • Blue line indicates a contextual spelling error. E.g. If we write Deer Mr Sen at the beginning of a mail, deer is a contextual error as ‘dear’ is the correct form of the word. The word is spelt correctly but used in the wrong context. To correct it: STEP 1: Right click on the word. STEP 2: A shortcut menu pops up which displays the suggested words. STEP 3: If you feel that the word typed is correct then click on Ignore All. STEP 4: You can also add the word to the dictionary by using Add to Dictionary. Figure 7.3 66 15-12-2017 12:06:41 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 72

There is a feature in MS Word 2007 that enables it to correct common typing errors automatically. For e.g. if the user types ‘teh’, MS Word 2007 will automatically correct it to ‘the’. If the automatic spelling and grammar check is not turned on, then follow the steps below: STEP 1: T ype a sentence in your document and include all errors. STEP 2: Select the text you typed.

8 ADDITIONAL LOGO COMMANDS Friends! You know to draw simple shapes using the basic commands of LOGO. Now, it’s time to learn some more useful LOGO commands. Let Us Start LOGO stands for Language of Graphics Oriented. It is the easiest and simplest computer language. We can draw, do sums, write and can do any kind of work with it. There are different types of computer languages, such as LOGO, BASIC, PASCAL, COBOL, C, etc. Since the computer does not understand our language, hence to work on a computer, we must learn a computer language. A language is a way of talking, writing or reading. Similarly, we will talk to our computer in LOGO language. A computer language is one, which a computer can understand. Do you remember how to get into the LOGO? Let Us Do1: Complete the steps to open the LOGO window. Now, try the following commands and find out what shape you get on the screen. Draw the shape in the given box. CS FD 50 RT 120 FD 50 RT 120 FD 50RT 120 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 79 73 15-12-2017 12:06:41

In this lesson We will learn many more additional LOGO commands such as Pen, Color, Print and Repeat commands. We will also learn the arithmetic operations in LOGO. When we work with LOGO on the computer, a triangle is seen in the centre of the screen. This triangle is known as TURTLE. Let’s meet our friend, the TURTLE. The centre of the screen is the Turtle’s home. The TURTLE moves all over the screen on our order. Whenever TURTLE moves on the screen, it leaves a trail. More on LOGO Commands We have learnt a few Primitives in the previous class. Let’s learn some more commands. SETH command is used to set the turtle’s head in any direction without using RT or LT commands. The SETH command is followed by a number which determines the number of degrees the turtle’s head will move. Format: SETH<space><number> We can use any number for setting the head of the turtle from any starting positions. SETH 90 turns the turtle right, SETH 180 turns it down and SETH 270 turns it left–all from the HOME position. Refer to the direction wheel. 74 15-12-2017 12:06:42 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 80

PEN and COLOR Commands We can move the turtle even without drawing anything. We can also change the color and size of the turtle’s pen. All this can be done using the Pen commands in LOGO. PENUP (PU) Command is used to lift the pen of the turtle up from the screen. As a result, the turtle does not draw anything. Format: PU Example: FD 40 RT 90 PU FD 40 PENDOWN (PD) Command puts the pen of the turtle down on the screen. The turtle can then start drawing again when given the command. Format: PD Example: FD 100 RT 90 PU FD 80 RT 90 PD FD 100 PENERASE (PE) Command makes the turtle work like an eraser. The turtle starts erasing instead of drawing as it moves. Format: PE Example: FD 100 PE BK 40 PENPAINT(PPT) Command is used after the PU and PE commands so that the turtle starts drawing again. Format: PPT Example: FD 100 PE BK 40 PPT FD 60 SETPENSIZE Command sets the pen size of the turtle. The size is specified in term of height and width. JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 81 75 15-12-2017 12:06:42

Format: SETPENSIZE [Num 1 Num 2] Example:FD 100 RT 90 SETPENSIZE [6 6] FD 100 RT 90 FD 50 Do You Know? The height specified in SETPENSIZE command has no significant effect on the turtle’s pen. Only the thickness of the pen is changed. PENNORMAL Command sets the turtle’s pen back to normal mode. After using any commands such as PU, PE or SETPENSIZE. We can use the PENNORMAL command to make it behave normally. Format: PENNORMAL Example: FD 100 RT 90 SETPENSIZE [6 6] FD 100 PENNORMAL RT 90 FD 50 SETPENCOLOR (SETPC) Command changes the color of the turtle’s pen. Colors are represented by numbers as given below. Color Codes in MSW LOGO 0 Black 1 Blue 2 Light Green 3 Light Blue 4 Red 5 Mauve 6 Yellow 7 White 8 Brown 9 Light Brown 10 Green 11 Cyan 12 Peach 13 Violet 14 Orange 15 Grey 76 15-12-2017 12:06:42 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 82

Let’s Practice Try the following commands and draw a green color mountain. SETPENSIZE [7 7] SETPC 5 RT 45 FD 50 RT 90 FD 50 LT 90 FD 50 RT 90 FD 50 LT 90 FD 50 RT 90 FD 50 SETSCREENCOLOR (SETSC) Command sets the background color of the Graphics screen. For example, SETSC 4 changes the background color to red. FILL Command fills a closed figure with the color of the brush. The color of the brush is set using SETFLOODCOLOR Command. Try both the above commands and check how these commands work. Do You Know? You can also set the pen size, color brush color and the screen color by choosing the appropriate options from the Set menu on the menu bar. PRINT Command PRINT command writes any text or number on the Logo recall list box. It takes only one input at a time. The input can be a number or text. Example: PRINT 50 This command will print the number 50 in the Commander window. If you want to print text, then follow this command in Input Box. PRINT “TEXT (or) PRINT [TEXT] Example: PRINT “LOGO The PRINT command can be written in short form as PR. So, PRINT 50 can be written as PR 50. If the text is more than one word then square brackets are compulsory. JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 83 77 15-12-2017 12:06:42

Arithmetic With LOGO Arithmetic operations can also be performed in LOGO. The symbols used in arithmetic operations are: Addition Operation: For addition, you can use sum or its operator (+) symbol. For Example: Add 40 and 50. Method 1: PR number + number or PR 40+50 Method 2: PR (SUM 40 50 60) Method 3: FD 40+50 Subtraction Operation: This operation is used to find the difference of two numbers. For Example: Subtract 40 from 50 Method 1: PR number – number or PR 50-40 Method 2: FD number – number or FD 50-40 Product Operation: This command will give the product of two numbers. For Example: Multiply 5 with10. Method 1: PR number*number or PR 5*10 Method 2: PR PRODUCT number number or PR PRODUCT 5 10 Quotient Operation: This command divides the first number with the second number and returns the result as a quotient. It will take two numbers as input. For Example: Divide 30/6 Method 1: PR number/number or PR 30/6 Method 2: PR QUOTIENT number number or PR QUOTIENT 30 6 REPEAT Command The REPEAT command is used as a shortcut in place of writing out the repeated commands. It saves a lot of time and effort. Instead of writing the same command again and again, we just write it once and specify the number of times it has to be repeated. 78 15-12-2017 12:06:42 JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 84

Consider this example: F D 60 RT 90 FD 60 RT 90 FD 60 RT 90 FD 60 RT 90 This will draw a square. We can write the commands below. REPEAT 4 [FD 60 RT 90] Glossary 1. Fill command: It fills a closed figure with the color of the brush. 2. PENUP Command: It lifts up the turtle’s pen up from the Graphics screen so that it does not draw anything. 3. P ENDOWN Command: It puts down the pen on the screen and the turtle starts drawing again as it moves. 4. PENERASE Command: It makes the turtle work like an eraser. P ENNORMAL Command: It sets the turtle’s pen back to the normal mode. 5. P ENPAINT Command: It is used after the PE and PU command so that the turtle starts drawing again. 6. P RINT Command: It is used to write anything in the Commander window. 7. Arithmetic operation: It is the mathematical work done on numbers. SETPENCOLOR command: It sets the color of the turtle’s pen. 8. SETPENSIZE command: It sets the size of the turtle’s pen in pixels. SETSCREENCOLOR command: It sets the color of the background of the 9. Graphics Screen. JSNR_181310004-_BGM_CSGK-G4-Integrated Book-Computers+GK-FY_WK_Text.pdf 85 79 15-12-2017 12:06:42
