In Emacs, how do I set the mark?

You can usually set the mark in Emacs by typing either C-SPC or C-@. If your terminal program does not let you type either of these keystrokes, or if they do not appear to have any effect, you can also set the mark by entering: M-x set-mark-command This will have the same effect as the single keystroke. You can check to confirm that Emacs has set the mark by checking whether the message "Mark set" is reported in the message line at the bottom of the screen.
