Hi,   
I update the profil with your suggestions...and it works :thumbup: 
So now : 
- Eject button works well. Thanks ddahlstrom !! 
- 'Changing windows' (I don't know how to say this better in English) button works fine. Thanks Gadroc 
- I correct a mistake on brightness for Shkval 
- I correct an other mistake for mod selector PVI-800 
- I add buttons for Abris brightness 
- I add a button for VAC ('s' key allowed VAC to listen you) 
- I add a selector for HUD mode but it doesn't work... and I don't know why, I double check arg, value, class type, I declare on export.lua file the ID button (9) and nothing. For this command, arg limit is strange -1,1 ??!! Possible value are -1.0, 0.0 and 1.0 ?! Am I right ?   
Here the files 
Update : keyboard.lua , export.lua, touchpal.xml, excel file about position and size of graphics, and pictKpaw folder.    
Thanks in advance for help !
