[openbox] A little direction requested = triggering action from overall window input events

[Jim Rees]

I know nothing about touchscreens but this is unlikely to be something you
would implement in openbox. Normally the window manager doesn't intercept
events and pass them on; rather the X server hands them to the application
that has focus. That's an oversimplification, but close enough.

I think you want something like xbindkeys, but smarter. It grabs X events
and performs actions based on a config file. It won't do what you want
because it has no notion of a magic sequence of events. But it would be
possible to build something like xbindkeys that does what you want, and I
imagine someone has done so.
