The keycode for what you're calling enter is spelled Return.
Look in /usr/share/X11/keysymdef.h at line 128 or thereabouts. If you don't
have that include file, install the X development headers. This will help you
find what the right spelling and capitalization are for anything you are
interested in. Keysyms are case sensitive, even though most things in the
keyboard definition are not case sensitive. I think Escape would work if you
had it spelled with a capital E.
The setup for the modifier keys is in /usr/share/X11/xkb/symbols/pc at line 39
where it assigns the Shift meaning to Shift_L and Shift_R the left and right
shift keys. Shift_L and Shift_R are assigned to keycodes right above there to
be whatever the keycodes <LFSH> and <RTSH> are on your keyboard model. The
Caps Lock assignment is there as well.
You can change which keys get assigned any of those meanings right there.
