Hello tojocky

If that is your situation

I think I understand you: when your program is running although hidden in the tray you want to open it by clicking some keys like the Ctrl+Ctrl used for Google Desktop, isn't it?

you can do this in Windows:

To monitor keys, for example left Control key, you have to call GetKeyState().

This function answers you if the key is pressed and if it is toggled (this serves too for keys that are not the Caps-Lock!).

A sample:

	char k = GetKeyState(VK_LCONTROL);
	if (k & 1)
		puts("Toggled");
	if (k & 128)
		puts("Pressed");

This works although your program is not focused, and does not affect to the normal keyboard use, I mean, you will not steal keys to anybody.

When your program is in the tray you can enter it in a loop that checks every 100 ms the Ctrl toggle state. If you detects toggle two times in less than 200 ms, voil�!
