  "Set up certain key bindings for PC compatibility.
The keys affected are:
Delete (and its variants) delete forward instead of backward.
C-Backspace kills backward a word (as C-Delete normally would).
M-Backspace does undo.
Home and End move to beginning and end of line
C-Home and C-End move to beginning and end of buffer.
C-Escape does list-buffers."
