I have got myself one of those flexible keyboards. It's great, impervious to dust an swarf.
One problem. It is not the extended version. Has no number keypad.
But what I did not think of is that it has no Page up or Page down which I use to jog the Z axis.
Is there a simple way to asign those actions to another couple of keys?
Prefer not at this stage to go making my own screens or any thing that complex.
