Emacs

• Emacs is a little more complicated. First you
  must have configured emacs in your startup script
• You must be running in a unix windows
  environment on Linux, SunOS, etc. or
• You must be running xwin32 tunneling with ssh on
  an MS Windows Machine
• Otherwise the mouse does not work.
• Most students will use pico from their home
  systems unless you purchase a commercial copy of
  xwin32.

Emacs

• At the unix prompt, type emacs filename and press
  return where filename represents the name of the
  file you want to open.
• You can start emacs without a filename.
• The mouse, if configured properly, works just as
  in most word processors.
• Note the "" is the control key. Control key
  commands are entered as a single key stroke in
  conjunction with other keys.
