key-bindings for 'undo

Hi there, who can enlighten me on the meaning and significance of (define-key global-map 'undo 'undo) in xemacs/lisp/keydefs.el please. Do some keyboards have a key labelled undo? I would like to make C-/ or C-_ show up in the pcl-cvs menu for undo. Currently the menu reads (partially): CVS ... Commit C Undo changes undo Add a I have looked for the undo key for months until I found C-/ and C-_ to work also. Can we do something about this? -- Adrian Aichner mailto:adrian＠xemacs.org http://www.xemacs.org/
