BindControl is a keybind and popmenu helper application that's been under development on and off since the mid and later years of live. It had been Homecoming-focused for the past few years, but recently I was prompted to add Rebirth support, which now exists in a usable beta form.
The whole thing is a constant work-in-progress, the Rebirth support doubly so, but if you're curious or intrigued, check it out, and file bugs and feature requests on the Github issues page.
Hit up the github page for a much more thorough description of BindControl:
