I have gotten hot keys to work through the Keyboard Inputs plugin for axis movement, however, there is no function for the space bar to be used as a feed hold?  Is this supposed to be automatically set?   

I'm using the stock screen set that came with Mach4 and the only things I have added are the hotkeys for axis movement. 

Thanks!

In case anyone is interested, after a lot of digging I finally found this to map keys to inputs and then code what you want to happen when those keys are hit.
