Shift-Alt-D - Disable AltD()
 Ignore an ALTD() in the program.
──────────────────────────────────────────────────────────────────────────────

 To use this option, move the cursor to the line of code that contains an
 ALTD() function and press <Shift><Alt><D>. A comment will appear on the
 right hand side of the ALTD() functions saying that the ALTD() has been
 disabled.

 When the program reaches this point, it will not stop execution, instead it
 will simply ignore the ALTD().

 Please Note: an ALTD() that has been disabled, is NOT ignored when running
              in Fast Run mode.
