I'm new to edit subtitles.
I have an interview fully written down.
Now i want to split it in .srt-lines of maximum 50 characters.
I would like to choose aegisubs to work with as many people recommend it... but i'm free to choose another program if that can do what i need.

i found the command edit/line/split/preserve but i dont manage to create a hotkey to use it. and then it still would be semi-automatic.
anyone can help out?
