Key Definition
 

How do I set up to use the mose wheel as jump forward/backward a few seconds like the key "<" ">" do ??

I set it up in the key definition page, but bsplayer still think that I want to re-size the window size.

I suggest either bsplayer warn me for multiple defintions or put the key definition in one of the column that I can click & sort by it.

if you're not in full-screen mode you will have to hold down the left mouse button at the same time as you scroll the wheel.

If I hold down left mouse button & roll the mouse wheel, the volume goes up/down.
