<P>Table 28.4 gives a brief listing of the major commands provided by <TT>emacs</TT>. <Esc><c> means to press and release the <I>meta key</I>—usually the <Esc> key on a PC keyboard, although on some keyboards you can use the <Alt> key and then press the following <c> key. <Ctrl-c> means to press the <Ctrl> key and the <c> key at the same time. Remember, pressing <Ctrl-g> at any time stops the currently executing command.</P>
