When Emacs gets hung, and I didn't know it was going to hang, so I
didn't turn on debug-on-quit, it would be great to have a keystroke that
would drop me straight into the debugger. As it is, these things can be
almost impossible to diagnose.

One possibility is to use `debug-on-event'.
It's not a keystroke, tho.

This is what I have:
,----[ C-h v debug-on-event RET ]
| Enter debugger on this event. When Emacs
| receives the special event specified by this variable, it will try to
| break into the debugger as soon as possible instead of processing the
| event normally through `special-event-map'.
|
| Currently, the only supported values for this
| variable are `sigusr1' and `sigusr2'.
`----
What version of Emacs are you using?
