Hi guys,
  At present, there isn't a VMD "mouse chord" mode that would allow
these kinds of manipulations without the mode switching, but I could
look into adding one. There are minor challenges implementing this across
all of the windowing systems, but it is doable with appropriate time spent.

One question I would ask is what mouse chords people would prefer as a way
of doing "translate while in rotate mode", or "rotate while in translate mode",

Charles Schwieters has an alternative mouse input scheme implemented in
VMD-XPLOR, which is a slightly modified version of VMD. For some time
I've wanted to unify his custom mouse input scheme with the standard VMD
mouse input scheme, perhaps allowing users to choose their favorite mouse
input scheme from a menu, for example. This would allow VMD to mimick
the mouse input schemes used by other tools, which may make it more
user friendly for people that make heavy use of other visualization tools
where they've grown accustomed to a different mouse input style.

If people have favorite mouse input schemes, I'd be happy to hear them
and to consider implementing them in a future rev.
