There is some documentation from nomachine, available at
http://www.nomachine.com/ar/view.php?ar_id=AR03C00172
The actions in my patch are named from their context in the source code,
but the relations to the descriptions on the nomachine page should
mostly be clear. But generally, I didn't look up what the keystrokes do
exactly, usually each keystroke sets some global variable which is then
used somewhere in the code. My naming of the actions is therefore mostly
based on the variable names, in the hopes of those being correct.

Doesn't the fullscreen mode do that? There is also some keygrab toggle,
but that seems to be a debugging feature.

No idea here either :)

I've introduced those ones, to be able to ignore Ctrl-Alt-Backspace or
similar bindings like the unpatched nxagent does.

There is no documentation on those, anywhere, so one would have to read
the code to come up with something. But since the actions are only
available with special compile time flags anyways, most people will
never be able to use them. I think its safe to just ignore those, I only
included them for completeness, so that my code is really able to
completely replace the old codepath.
