<Shift><F2> used to be the Grey Wolves keys, and TMO (Ducimus) copied a lot of SH3 things, including his keyboard layout. You could try that, but if clicking on the screen doesn't take you to walk-around in TMO, I'm not sure a key combo would work either... You could look in Game / Data / Cfg / Commands.cfg for keycodes, or use the ReadMe for notes on the interior, if they mention it...
