You can use Vim to control VLC and edit song lyrics or audio transcripts:
- You can add audio timing information to each line of text transcript.
- You can cue VLC audio to the time/line you are editing.
You will need:
- Vim to edit text.
- Perl to connect gvim to vlc via a socket.
- VLC.
Below: Modify the path to Perl and Vim script according to the directory you save them in.
Setup vlc to listen on a socket[]
" VLC setup: $ vlc > tools > prefs > main interface > enable RC, " Tcp-Input=[localhost:2150] .. ~/vim/vlc.pl will open this socket. " Console: [donot_open] console

That's a lot of script for a tip. I have done some quick formatting, but have not thought about the proposed tip yet. One point is that the "Mosh" function names are a bit jarring and should be replaced with s:
