I have a USB pendant keyboard which I bought from a Chinese seller who claimed it would work for Mach3.
It emulates jog xyz, jog rate  and a few other functions.
Everything works except jog rate.
When I push "Jograte down" Jograte goes up, and when I push"Jograte up" nothing happens.
Clearly the transmitted codes are incorrect and I cannot find a way to change the MAch3 hotkey codes. Some programs I downloaded (screentweak, machscreen ) always seem to have the wrong version number to enable me to do what I have to do(change hotkeys in Mach3).
The pendant transmits code 221 for "jograte down" and 187 for "jograte up" and I think Mach3 expects code 221 for "jograte up" and 219 for "jograte down" whenI'm not mistaken.
So does anyone know a method to make this work?

Hello,

if your screenset isn't protected by a passord, you can change the hotkey with MachScreen. Here is an example using the Standard screenset 1024.set:

goto page 50
select button Dn( at pos 429, 187
hit button "Hotkey direct" at the bottom of the property dialog
enter the hotkey code and hit "Ok".

Thanks Klaus, it's solved.
 I missed the extra "(Dn " and "Up)" buttons on page 50.
