Just be aware that there is a pin halui.mode.teleop that can be used to select (eg enable) the jog mode. If you set this pin when using gmocappy it will change tabs to the jog screen.
My pendant has a yellow safety button that must be pressed to jog. I use that to set this pin cos I was sick of having to walk back to the screen to select the jog screen.
Linuxcnc ignores the MPG when running programs etc.
