Douple tap spacebar to play from beginning, when the CTI is at the end of your time line
When the CTI (Current Time Indicator) is at the end of your timeline pressing space will start playing your video from the beginning. I find that this often can be annoying and would prefer if pressing space in this situation would move the CTI to the beginning, but not play, then pressing space again would start playing. This would give you the option, if you pressed spacebar at the end, to go oh wait, I don't want the CTI at the beginning of my video.

Under Preferences > Timeline, you can disable this default behaviour, by switching off: "At playback end, return to beginning when restarting playback".
If you disable this, the playhead will not annoyingly jump to the beginning, and require you to press Home first.

This would be VERY annoying behavior. The current Home shortcut does the job.
