{ These are the Editor functions that I have defined so far
  If you want to add another one, do the following:
    1. Give it an identifier (below)
    2. In WESETUP, in the function FINDFUN(), add a "description" of it
       that will be used in the .KEY files
    3. In WEFUNCT, in DoFun(), add into the CASE statement code to handle
       your new function.
    4. (optional) also in WEFUNCT, in LineEdit(), add the same code
       This will allow your new function to be used in places where only
       a line is being edited (<E>dit in spell checker, Insert File, etc)
