To help you create your own custom keymaps, I updated @Slion's excellent keyboard map for the Pro1-X QWERTY layout and added the key numbers for each of the six modifier keys ('F logo' Fx, Shift, Ctrl, Alt, and right and left "yellow arrow" Fn). Remember that the two Shift keys are actually the same, as are the two Ctrl keys. Unfortunately, you can't map right and left Shift to different key codes, or right and left Ctrl either 🙁
