Hi Berty,
no name calling here, everyone needs to start somewhere and Mach being so versatile has a huge learning curve, I have been using it for years and still only know half of what you can do.
Ok the Mach3 folder I was talking about is the location you installed Mach3 to, if you kept the default install location it will be C:\Mach3
I think there may be info on using KeyGrabber in the Mach2 Customisation manual which you should find on the document download page.
