What launcher / home replacement are you running? If its Nova, long press on the desktop and choose "nova actions" - then choose app drawer, once the shortcut is created you drag it to your tray. If its another launcher it probably has a similar ability to create action shortcuts. Someone else will have to chime in on your particular version as I don't know how Apex or other launchers handle it.
Trebuchet via CM10.1 Long pressing does nothing and am unable to find a setting. Even tried reinstalling the latest nightly. Still missing...
Well I ended up doing a factory reset and recovery from a backup that was 2 days old. All is well that ends well...
