lew,
you could also create a button and set it off screen so it's not visable and give it any "hot key" you want in Screen desighner.....
In Mach under "Config"/"GenConfig" there is a setting for "no system menu", it warns that you'll want a button if you ever want the menu back
Or put code in the macro pump..
Some thing like this but haven’t tried it might be a better code, just an idea
Private Sub_KeyPress(KeyAscii As Integer)
If (KeyAscii = 13) Then
Call SetVar(1, 0)
DoOEMButton(348)
Else
Call SetVar(1, 1)
DoOEMButton(349)
End If
End If
End Sub
