Thank you for the response.

The "manual" that was sent with X-keys Pro was a single sheet of paper. I'm not sure what you mean by "Escape+Left shift." The help file that comes as part of the application doesn't really say much.

Macro Works does have a repeating key option, but it barely nudges me forward, and that's set at the maximum of 25 presses per second.

Can you help me out with what you mean by "Escape+Left shift?" Thank you!
