Subtitle button in control panel?

[Lowtz]

Hi, I'm new to this forum and I got my first question about VLC.

I wanted to ask if it's possible to add a button to the vlc control panel interface that switches on/off the subtitles of a video?

I got some .mkv files with subtitles in it, now I really would like to have a button on the CPI to turn the subs in the movie on or off.
The only button I found was something to open subtitles, but I don't have any subtitle data, because they are IN the file.

I hope you guys know what I mean and you can help my with that.

Greetz,

Lowtz
