Example 1:
module_keyDownEHId = displaySetEventHandler ["KeyDown", "_this call module_keyDown"];
Example 2:
#include "\ca\editor\Data\Scripts\dikCodes.h"

moduleName_keyDown = 
{
	private["_handled", "_ctrl", "_dikCode", "_shift", "_ctrl", "_alt"];
	_ctrl = _this select 0;
	_dikCode = _this select 1;
	_shift = _this select 2;
	_ctrl = _this select 3;

	if (!_shift && !_ctrl && !_alt) then
	{
		if (_dikCode in ([DIK_F]+(actionKeys "NetworkStats"))) then
		{
			nul = [_ctrl] execVM "path\script.sqf";
			_handled = true;
		};
	};

	_handled;
