Keyboard shortcuts for transport? (Play, Pause, Stop)

[Boscop]

Thanks for this great midi editor :)
Are there any keyboard shortcuts for the transport (Play, Pause, Stop)? (Like in DAWs.)
I wish I could use the space bar to play and pause because it's SUCH a common operation, using the mouse takes much longer every time.
Proposed semantics:
When stopped, pressing space bar plays from stop location.
When playing, pressing space bar pauses, cursor stays at current location.
When paused and pressing space bar, if shift is pressed, it should continue from the paused location, otherwise start playback from the stop location.
