As I setup a game today in DOS-Box, I pressed CTRL-F1 and may have locked out the keyboard from being used.

Retropie sees the keyboard and it can be used until the DOS-Box emulator starts up.

I added US keyboard to the settings and that didn't change the state.

I even uninstalled, restarted Retropie. Installed DOS-Box and restarted Retropie. No change in the keyboard.

I do have access to the keyboard mapping through DOSBox-Staging.

Is there a way just to erase the keyboard mapping file that it created in DOS-Box?
