maybe you could plant in an engine like the one in Tactical Ops. That has a special engine on what you can define every button, and thus also make a button that when you pres it automaticly typs \"/shout HELP ME!!! MY ASS IS ON FIRE!!!! stupid fire elementals.....\"
It would also make moving easier, since you can define those controls to the buttons you like best. Also you can set your own mouse-speed when using mouselook, cause for my feeling the mouselook is extremely slow now. i am used to a 25.5 mousebutton, and in the game it moves like a 0.5 or so
