Making, Saving, and Naming Documents 95 Notable Note Most of the time you'll type in Insert mode; whatever you type is added at the insertion point, and surrounding text scoots over to make room. If you accidentally shift to Overstrike mode, whatever you type replaces existing text. In most programs, the status bar (at the bottom of the window) displays OVR when you are in Overstrike mode. Double-click OVR to switch back to Insert mode. If OVR is not displayed, try pressing the INS key to change modes or check the program's help system for instructions. Zooming In and Zooming Out Nothing is more annoying than text that's too small to read or so large that it runs off the right edge of the screen. Of course you could change the size of the text (as explained in Chapter 12, "Sprucing Up Your Documents with Formatting"), but that changes the size on the printed copy as well. The solution is to change the display size. Most programs offer controls that enable you to zoom in on a document so you can see what you're typing, or zoom out to get a bird's eye view. Check the menus and the button bar for zoom controls. Skipping Around in a Document Being in a document is like squeezing your way through a crowded city. You have all these char- acters onscreen elbowing each other for a peek at the parade. You are the insertion point, attempting to weave your way through the crowds. To move the insertion point, you have several options: · Mouse pointer--To move the insertion point with the mouse pointer, move the pointer to where you want the insertion point and then click the left mouse button. · Arrow keys--The arrow keys let you move the insertion point up, down, left, or right one character at a time. · Ctrl+Arrow keys--To move faster (one word at a time), most programs let you use the Ctrl (Control) key along with the arrow keys. You hold down the Ctrl key while pressing the arrow key to leap from one word to the next. · PgUp and PgDn keys--Use the PgUp key to move up one screen at a time, or use PgDn to move down one screen at a time. Remember, a screen is shorter than an actual page. · Home and End keys--To move at warp speed, you can use the Home and End keys. The Home key usually moves the insertion point to the beginning of a line. End moves the insertion point to the end of a line. Most programs also offer a scrollbar, as shown in Figure 10.2, that enables you to page up or down. However, scrolling does not move the insertion point. You must click the spot where you want the insertion point moved.
