Autohotkey - remap a solid key
Yes, it should be possible.
Once an AutoHotkey script is running, open the running program from the tray icon.
Tray Icon > Open
Menu > View > Key History
This will show a history of keystrokes.
Press both keys of interest (as noted in the original post) and then refresh the Key History window. The two keystrokes should show up as two different SC values which can then be used for two different hotkey definitions.
This is offtopic but you could remap those keys with Sharpkeys. It will let you change keys in registry.
