I use Page Up and Page Down on my Logitech G9 mouse as well as the End key. When I try mapping End to Map, Page Up to Roll and Page Down to Revert they appear as blank entries but still work in the game.
When I reload the game these keys don't work anymore and I have to set them again. I tried manually setting them in the usersettings.xml file but as soon as the game starts is blanks them out as, for example:
<Action name="WorldMap" input="0 0 KEY_DOWN 0 " />
