The only downside however is that the key it presses is hard coded as the letter “A”, not exactly the best key since most gamers run with WSAD to move around and for about a week I was beginning to annoy people by every time I pressed ‘A’ to move around I was transmitting. A quick dig through the code shows us where the key is defined, currently on line 17…

#define SIMULATEKEY XK_A // Simulate Key Press

Excellent, so changing this should’nt be too hard. After a quick search around I found a nice long list of all the codes that you could use instead of “XK_A”…

Now obviously, over half of those are going to be quite useless as they will create key-presses resulting in keys being randomly typed. The best ones that I have found for use with Ventrilo & games are…

XK_Pause
XK_Break
XK_Num_Lock
XK_KP_5
XK_Shift_Lock

99% of the time these keys will have no effect on your games at all, so they are the safest keys to use for transmitting. Personally I use “XK_KP_5″ which is the same as pressing the number 5 on your keypad when num lock is off, ie. nothing happens. Using that key also doesn’t mean you have to have num lock off either as this is a simulated key press, so unless some game gets clever, or you use the num pad and have assigned this key to something else, its possibly the best key to use for Push-To-Talk since it does not get used for anything.

So to change the key all you do is replace “XK_A” with whatever you want to use, then “make” and “make install” and you’re done
