I've got mach 4 running on my machine but I can't seem to get "go to work zero" in the mode tabs.  Also i can't get any keyboard functions to work.  I did configure everything I was thinking it needed.  I've attached some photos to show what I did.  Any help would be appreciated.

It doesn't seem you've ENABLED keyboard jogging. See that black icon in the tray with the red circle? Click that. You can also do it in the Jogging tab in the center of the screen.
