Hi! I've been trying to find a reliable way to search and open terminal or any other applications in OSX. The way that is being used which is CMD-SPACE is risky because this is a default shortcut that any one can change. However, Fn-F4 (Launchpad Key) is always working and easy to search for application from any window or app without running to an issue if the other app is using CMD-SPACE. I wonder if there's a way to add Fn key so we can combine it with F1-F2... keys. Thank you! AJ
