This worked well on 3.2.2 <Ubuntu> 20.10. Recommended.
First import video with:
``
aegisub-3.2 ourbigbook-parent.mkv
``
They don't have an `aegisub` executable without the version number. Amazing.
If you already have a subtitle file that you want to edit, then just pass it on as well:
``
aegisub-3.2 ourbigbook-parent.mkv ourbigbook-parent.ass
``
Ctrl + P: play and pause video.
Ctrl + 3: set current substitle start time.
Ctrl + 4: set current substitle end time.
Enter: finish editing the current entry and start a new one.
