I recently purchased this 33 key silcone keyboard to jog around while Im in my cnc room.  I know tab brings up the jog/step menu but I cant see the monitor is there a keyboard shortcut to toogle between jog and step for fine adjustments?  Will ctrl J toogle modes can kestrokes be edited in the config screens?

You can add keyboard shortcuts by editing the onscreen buttons in one of the screen designers. Be careful though  that the keystrokes you choose are not used for anything else.
