Second key-binding change is:

  bzr diff -r 1737.8.2..1737.8.3

which introduces a bit of helper code too, including a 50 ms hard-coded timeout. However, the whole things seems to hinge upon:

  optionGetShowHud().key().toString() == action->key().toString()

which doesn't seem to be capable of expressing the requirement "Press and release of Alt with no other keys touched (pressed, or released) in the meantime.
