Hi Cal,
I asked about that Holger recently so here is his answer:

Not really. Most operating systems have low-level keyboard routines,
but then you have to deal with platform-specific encodings, i.e.
you no longer get ASCII codes. At the moment we do not plan to support
this any time soon.

So no good news for us :(... No quality keboard control in multimedia
projects.
I think the solution will be Rebol's own keyboard handler or at least simple
mezanine function - "platform specific keypress decoder" which will read
low-level keyboard codes and convert them into rebol key-events or something
like that.
(What's your opinion on that Holger?)
BTW I tried to use SHIFT and CTRL keys with combination of other "common"
key to achieve multiple keypresses but there are platform diferencies of the
keyboard behavior too :( ie. when I wrote kb-handler under WIN port of /View
and tried under Amiga and Mac I was unable to control the aplication in the
way how it works on WIN.(I haven't test it under Linux yet so I don't
know...)
