	Editing Source Code

	One of the main reasons for the success of Microsoft Windows is the graphical user interface (GUI). Windows 98/95 has introduced a modified GUI, but one that is intuitive to the experienced Windows user. A consistent user GUI means that when a particular feature appears in two different applications—for example, a Windows word processor and the Visual C++ IDE editor—that feature usually has the same menu and keyboard commands, in the same locations, in both applications.

	This means that even if you have never used the Visual C++ IDE editor, you should find that correcting mistakes or moving to the end of a line, the beginning of a line, or the bottom of the edit window is just as easy and familiar as it is in your favorite Windows word processor.

	Here are some helpful tips for working with the Visual C++ IDE editor. To move quickly through a line, hold down the CTRL key while pressing the left or right cursor key. This causes the edit cursor to move to the right or the left (depending on the cursor key pressed) one whole word at a time. (A word is defined as anything delimited by a blank space or punctuation.)

	To delete an entire word instead of a single character, place the cursor on the space before or after the word to be deleted and press either ctrl-delete (to delete the word to the right) or ctrl-backspace (to delete the word to the left).

	To allow for the maximum amount of editing workspace, the horizontal and vertical scroll bars can be turned off (see Tools | Options). If you chose this option, the mouse cannot be used to scroll the window, either horizontally or vertically. For this reason, you need to know two key combinations: ctrl-page up, which moves you to the top of a program; and ctrl-end, which moves you to the bottom of a program. How are you doing with that highlighter?

	Perhaps you are wondering why we have made no mention of the horizontal movement keyboard equivalents. There is a reason: Most professionally written code fits within the standard monitor’s 80-column width. This makes for easy reading and code debugging—since each line of code is completely visible, there can be no hidden bugs in column 95.
