2.1.4 Centering the Display

C-l, the recenter command, puts the current line in the center of the window vertically. This feature is useful if you're typing at the bottom or the top of the display. Typing C-l quickly moves the material that you care about to the middle of the display, where it is easier to see the full context.

C-l also redraws the display, if for any reason it appears obscured or contains random characters. This doesn't happen as often as it used to when we used terminals, but it can be a handy thing to know about, especially if you find yourself using Emacs remotely in a terminal interface.

Table 2-2 lists cursor movement commands. If the command is mnemonic, the word to remember is given in italics.
