I'm not familiar either.  Thanks for the suggestion.  I've tried
adding a few things like

Control-x: tui-switch-mode

to my ~/.inputrc without any luck.  However, it seems that

1. Run 'gdb'
2. Hit Escape to enter vi command mode
3. Hit Control-E to enter Emacs mode ('emacs-editing-mode')
4. Hit Control-x a to enter the TUI

works.  Though now I'm in Emacs mode and hitting Control-x a again
does not exit the TUI.  And I can't seem to get  "M-C-J" to trigger
vi-editing-mode again (though this is likely me being an idiot).
