Kodi (A.K.A. XBMC) is a wonderful media center software that can do pretty much everything about the home entertainment and more. I am using a wireless mouse to control a laptop connected to TV. One annoying thing is that the mouse wheel is linked to forward/backward in the video playback. This leads to some sudden jumps in playback when I accidentally hit the mouse (wheel). Meanwhile, there is no mouse action that can controls the volume up/down easily. I have to either uses the keybaord (i.e. stand up and step forward) or use the TV/receiver control (i.e. fumble around). It finally get to the point that I have to find a solution. After some search and experiments, particularly thanks to the excellent explanation on the
wiki (http://kodi.wiki/view/keymap) I was able to change the mouse wheel to control volume. Here is what I did:
<?xml version="1.0" encoding="UTF-8"?>
<keymap>
<fullscreenvideo>
<mouse>
<wheelup>VolumeUp</wheelup>
<wheeldown>VolumeDown</wheeldown>
</mouse>
</fullscreenvideo>
<!--Change the video control -->
<videoosd>
<mouse>
<wheelup>VolumeUp</wheelup>
<wheeldown>VolumeDown</wheeldown>
</mouse>
</videoosd>
</keymap>
There are several posts talking about the <fullscreenvideo> window (http://kodi.wiki/view/keymap#Windows), which controls the behavior when there is no menu. But often any movement of the mouse first activates the <videoosd> window, and we have to change the wheelup/down in that window as well. Otherwise, you still get forward/backward bahavior. Hopefully this can help you as well.
