Actually I think we should keep your quick seek(qs) stuff.
That quick seek you added calls Seek() without pausing while
my QuickSeek keys '<','>' call QuickSeek() (and
you should
be paused first or you will get an assert).

I think all 3 seeks are useful for testing the engine.

It really is amazing how simple player is not simple at
all anymore.  I wonder
if it is time we create a new
RSPlay (really simple player) to give newcomers a truly
simple example of how to use the platform to play back
content.
