Use to work on two parts of a program, or two programs, simultaneously. Split divides the View window horizontally. Use F6 and Shift+F6 to move between the windows on the screen: ■ F6 moves the cursor down through the windows. ■ Shift+F6 moves the cursor up. To restore an unsplit View window, choose Split again. The active window contains the cursor. This window can be sized from the keyboard: ■ Alt+Plus(+) expands it one line. ■ Alt+Minus(-) shrinks it one line. ■ Ctrl+F10 expands it to fill the screen, or returns it to its former size.
