Left mousebutton broken after liquid-accident

[kjempe]

Hi Folks.

I accidentally spilled some amount of soup over my R50e. The Good news is that the keyboard is - after some cleansing - fully functional again. The bad news is that the left mousebutton is not working. Middle and right button plus trackpoint are working though.
In case the buttom won't start working again - does anyone know how to tell Gnome to recognise the middle button as left button? Would be great if an external mouse had all three buttons working.
