Emacs is the recommended editor for UNIX. The x-windows versions,
xemacs and d0emacs have nice menu options such that
learning the Emacs commands is virtually unnecessary.
The best tutorial is simply to open a file and play.
To setup and invoke the x-windows version of emacs, type:
% setup xemacs
% xemacs filename
Remember that in order to run an x-windows application, the DISPLAY
environment variable must be set appropriately. To see its current definition,
type:
%printenv DISPLAY
To change the DISPLAY variable:
%setenv DISPLAY your-graphical-terminal:0.0
See the UNIX at D0 page for more editing details.
