(Filing here because there don't seem to be any bug reports on Trac.)
It's pretty simple: There's no way to assign a keyboard shortcut to play the
animation, forwards or backwards. You can only rightclick+hold on the relevant
button.
A keyboard shortcut would be useful, already, and it would become more so if
animated editing is implemented (eg. tracing the path of an object using
continuous or discontinuous hand-drawing as the animation plays)
IMO this keyboard shortcut should function as a toggle:
* is animation playing?
* if it is, but not in this direction, switch direction.
* if it isn't, start it playing.
* if it is, and in this direction, stop animating.
More troublesomely, it should also (at least for the time being) block image
modifying actions, and any 'transactional' actions (eg. interactive brush
stretching).
