Which of the following programs should be used to create a business letter
Whether you're writing a letter or calculating numerical data, your keyboard is the main way to enter information into your computer. But did you know you can also use your keyboard to control your computer? Learning a few simple keyboard commands(instructions to your computer) can help you work more efficiently. Show
How the keys are organizedThe keys on your keyboard can be divided into several groups based on function:
The following illustration shows how these keys are arranged on a typical keyboard. Your keyboard layout might be different. Typing text
Key name How to use it Shift Press Shift in combination with a letter to type an uppercase letter. Press Shift in combination with another key to type the symbol shown on the upper part of that key. Caps Lock Press Caps Lock once to type all letters as uppercase. Press Caps Lock again to turn this function off. Your keyboard might have a light indicating whether Caps Lock is on. Tab Press Tab to move the cursor several spaces forward. You can also press Tab to move to the next text box on a form. Enter Press Enter to move the cursor to the beginning of the next line. In a dialog box, press Enter to select the highlighted button. Spacebar Press the Spacebar to move the cursor one space forward. Backspace Press Backspace to delete the character before the cursor, or the selected text. Using keyboard shortcutsKeyboard shortcutsare ways to perform actions by using your keyboard. They're called shortcuts because they help you work faster. In fact, almost any action or command you can perform with a mouse can be performed faster using one or more keys on your keyboard.
Find program shortcutsYou can do things in most programs by using the keyboard. To see which commands have keyboard shortcuts, open a menu. The shortcuts (if available) are shown next to the menu items. Keyboard shortcuts appear next to menu items. Choose menus, commands, and optionsYou can open menus and choose commands and other options using your keyboard. In a program that has menus with underlined letters, press Alt and an underlined letter to open the corresponding menu. Press the underlined letter in a menu item to choose that command. For programs that use the ribbon, such as Paint and WordPad, pressing Alt overlays (rather than underlines) a letter that can be pressed.
Useful shortcutsThe following table lists some of the most useful keyboard shortcuts. For a more detailed list, see Keyboard shortcuts.

Equivalent to right-clicking the selection. Using navigation keysThe navigation keys allow you to move the cursor, move around in documents and webpages, and edit text. The following table lists some common functions of these keys. Press this To do this Left Arrow, Right Arrow, Up Arrow, or Down Arrow Move the cursor or selection one space or line in the direction of the arrow, or scroll a webpage in the direction of the arrow Home Move the cursor to the end of a line or move to the top of a webpage End Move the cursor to the end of a line or move to the bottom of a webpage Ctrl + Home Move to the top of a document Ctrl + End Move to the bottom of a document Page Up Move the cursor or page up one screen Page Down Move the cursor or page down one screen Delete Delete the character after the cursor, or the selected text; in Windows, delete the selected item and move it to the Recycle Bin Insert Turn Insert mode off or on. When Insert mode is on, text that you type is inserted at the cursor. When Insert mode is off, text that you type replaces existing characters. Using the numeric keypadThe numeric keypad arranges the numerals 0 though 9, the arithmetic operators + (addition), - (subtraction), * (multiplication), and / (division), and the decimal point as they would appear on a calculator or adding machine. These characters are duplicated elsewhere on the keyboard, of course, but the keypad arrangement allows you to rapidly enter numerical data or mathematical operations with one hand.

Three odd keys So far, we've discussed almost every key you're likely to use. But for the truly inquisitive, let's explore the three most mysterious keys on the keyboard: PrtScn, Scroll Lock, and Pause/Break. PrtScn (or Print Screen) A long time ago, this key actually did what it says—it sent the current screen of text to your printer. Nowadays, pressing PrtScn captures an image of your entire screen (a "screen shot") and copies it to the Clipboard in your computer's memory. From there you can paste it (Ctrl + V) into Microsoft Paint or another program and, if you want, print it from that program. More obscure is SYS RQ, which shares the key with PrtScn on some keyboards. Historically, SYS RQ was designed to be a "system request," but this command is not enabled in Windows. Tip: Press Alt + PrtScn to capture an image of just the active window, instead of the entire screen. ScrLk (or Scroll Lock) In most programs, pressing Scroll Lock has no effect. In a few programs, pressing Scroll Lock changes the behavior of the arrow keys and the Page Up and Page Down keys; pressing these keys causes the document to scroll without changing the position of the cursor or selection. Your keyboard might have a light indicating whether Scroll Lock is on. Pause/Break This key is rarely used. In some older programs, pressing this key pauses the program or, in combination with Ctrl, stops it from running. Other keys Some modern keyboards come with "hot keys" or buttons that give you quick, one-press access to programs, files, or commands. Other models have volume controls, scroll wheels, zoom wheels, and other gadgets. For details about these features, check the information that came with your keyboard or computer, or go to the manufacturer's website. Tips for using your keyboard safely Using your keyboard properly can help avoid soreness or injury to your wrists, hands, and arms, particularly if you use your computer for long periods. Here are a few tips to help improve keyboard use:
