SetupKeys.exe is not-user-friendly program to configure DoomGL, WinHeretic & GLHeretic.

Here how it works:

Edit the hereticrc.cfg (or doomrc.cfg) file.
Run SetupKeys.exe.
Type the key you want to assign. In the window a line "KD: <code>" will be displayed.
Copy this code in hereticrc.cfg (or doomrc.cfg).

Example:
You want to assign the H key to FIRE:
You press the H key under SetupKeys, it displays: "KD: 72"
In hereticrc.cfg (or doomrc.cfg), at the line key_fire, you write: "key_fire 72".
