Day 5 Emacs Editor David A. Gaitros Department of Computer Science Florida State University

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.
