Because at first, this tool was written for the purpose of making timecoded lyrics from Japanese songs, there's a lot of helper functionality built in. Also, much of shortcuts built in are leftovers of my old tools program. Some of it isn't used that often anymore.
There are two text panes, but the left one is the main one where you'll be working the most.
The right one is only for conversion purposes. The right one also doesn't support any of the shortcut keys.
