Using Emacs to Log in to io for Haverford upper-level CS courses

• If you have not used emacs before, get an emacs startup file from my directory with the command "cp ~dwonnaco/.emacs-cs355 ~/.emacs".
• If emacs is not already running, start it by typing "emacs" in a terminal window that you've created using telnet or eXodus, or by selecting emacs from the pop-up menus if you're running eXodus.
• If you want to interrupt a running command in emacs, use control-g. This is perhaps the most important thing to remember when you're learning emacs. Note that, if a command is waiting for input, the emacs cursor must be in the "minibuffer" (the single line at the bottom where commands get input) for control-g to work. For example, if you type control-x control-f, emacs will prompt you for the name of a file to open. If you type control-g immediately, you'll cancel the "find-file" command. However, if you click the mouse in another window in emacs, the emacs cursor will move there, and control-g will no longer cancel the find-file (you may see the word "Quit" in the minibuffer, but then the find-file prompt will return). You'll have to click back in the minibuffer and then type control-g to cancel the find-file.
• When emacs is running in X or eXodus, the mouse buttons have the following functions in most buffers:
  • 1st button: select the start of a region of text to be cut or copied
  • 3rd button: select the end of the region to be copied (double-click cuts the text)
  • middle button: paste the text that was just selected or cut
• Experiment with the pull-down menus in the emacs window (not on the Mac menu bar) if you're running emacs within an X or eXodus session.
• For an introduction to emacs keystrokes, run the emacs tutorial (on the "help" menu, or by using control-h followed by "t" if you're not using X or eXodus).
