HELP!
  somewhere exists a chart of all the mouse pointer inputs (Mach commands) and the keystrokes I need to use to simulate those inputs...but I can't find it.
  Probably the simplest of which is "ALT-R" for "start" & "tab" gets me the jog screen....
 I need to tie the "Ref All Home" command into my PLC control circuit (and the IPAC) to prevent further crashes.
         many thanks in advance for your help.....George P.

I think they are in the customisation manual, it gives you the scan codes and you have to look them up in an ascii table.

BTW the Home key on your keyboard should be the key for referencing all axis.
