My idea would be to create a xkeydefs.sl file for the Key-combinations that
work only under X-Win.

Take keysymdef.h and modify it in jed (with regular expression replacement
or rectangle commands) from

#define XK_BackSpace                0xFF08        /* back space, back char */

to

static variable XK_BackSpace =                0xFF08        % back space, back char

and so on, for all keysyms that are supported by jed. John E. D. wrote:

The next step would be to define strings for all the supported key-combis.
The problem is, that I don't know of any standard for a terminal emulation
that defines strings for all of them :-(

The last step would be to bind the keysyms to the strings.

   x_set_keysym (Int_Type keysym, Int_Type shift, String_Type str)

All in all a pretty long file...

After this, the user only had to do

  require("x-keydefs")
  
in order to bind something to Key_Shift_Enter and the like.

My dream solution would be to have a function, that does the required steps
automatically, so I could do for example

#ifdef XWINDOWS
x_definekey("<Shift><Enter>", "open_fold");
#endif
