Nice idea, I have some suggestions for improvement though:

It would be nice to have these for all the X keycodes (is there a list of
them somewhere). Also, I wouldd prefer them in variables with some X in the name,
or even better in an associative array, like

  variable X_key = Assoc_Type;
  X_key["Left"]  = 0xFF51;
  X_key["Right"] = 0xFF53;

and so on, for all the keys defined in keydefs.

This seems pretty nonstandard and may couse problems 
(does your <C> key work after binding this to a function?)
    
Looking at keydefs and the undocumented x_set_keysym feature, 
I suppose something like

  variable Key_Ctrl_Shift_Home        = "\e[1%";

might be a better choice. I don't know about a good one for Left, Right,
Up, Down, though.
                                          
It would be nice, to have them all included in keydefs.sl.
(Are there windows keystrings for Shift_Ctrl_something?)

> x_set_keysym (KB_Right, '%', Key_Ctrl_Shift_Right);

this would become

  x_set_keysym (X_key["Right"], '%', Key_Ctrl_Shift_Right);
  ...
  
and could go to a file x-keysyms.sl to be usable by a wider circle...

Nice.
