gotcha okay couple of options, first I just tried this and i worked, i'm also on openelec and using confluence skin so if you want to launch fullscreen automatically after selecting a music track you need to follow these instructions
using filezilla(or something your familiar with) go to
/usr/share/xbmc/addons
right click on skin.confluence and chose download
now in your downloads folder you should see "skin.confluence"
go into this folder and where going to change one file and add a file
in addons.xml
in the third line change
id="skin.confluence
to
id="skin.confluence.mod
now create a file and call it Custom_MusicFullscreenEnabler.xml
place this code in the file
Code:
<window type="dialog" id="3001">
<allowoverlay>no</allowoverlay>
<onload condition="!Window.IsActive(visualisation)">FullScreen</onload>
<visible>Player.HasAudio</visible>
<controls></controls>
</window>
(code thanks to `Black from
http://forum.kodi.tv/showthread.php?tid=...pid1473763)
place this file in 720p (might be 1080i/p in skin confluence folder) okay now change the folder name from skin.confluence to skin.confluence.mod
now right click on folder and compress to zip file
place the file back into openelec and install the zip(system add-ons, install fom zip file, locate it and click)
say yes and voila you have automatic fullscreen on music.
now whenever you've selected a track you'll be in visuliser so just edit the keymap file like you did before and add buttons
<Visualisation>
<keyboard>
<browser_back>Stop</browser_back>
</keyboard>
</Visualisation>
so you mapped browser_back to stop you can map anything else effectively having a custom remote just for the visulisation window
you might also want to see what the action "osd" does
eg
<browser_back>osd</browser_back>
report back if you get stuck
