Can't search in the lyrics

[kupsef]

Would be a nice feature to be able to search in the displayed lyrics.

My use case (I don't know how common it is):
I leave the lyricfier open in the background, while listening to several different songs.
When I don't understand a part of the song, I want to find the location of it quick.
I know the surrounding of the unknown part, so I could find it quick if I had the opportunity to search the lyrics.
