[755-1] updates to the hotkeys

[Ross Dickson <dickson@cs.wisc.edu>]

I have made a number of updates to my set of ic station hotkeys in
~dickson/mgc/ic_hotkeys/

Highlights of this update include path editing keys. Future updates
will be made without notice.

The key files are all named key_[letter]{s}.ample
The file "list" is a list of what the keys do generated by head -1 key*
which is also in postscript in "out.ps"
"big" is the text of one of the mentor provided sets of keys in custom
hotkey format, "small" is the same list with most of the functions I have
assigned to keys removed. Note that all the defined hotkeys are on the
left hand because I use the mouse with my right hand.
