Hello there..I'm wondering if it's possible to customise one of the Function keys to paste a preset message whenever I press it. I'm always having to type in one same message to vendors whenever I buy something online, which is to leave the parcel by the door and not to send to the post office if nobody is home for delivery. I want to program a pre-set message into one of the function or hotkeys. Is it possible to do that? I have an iMac running mountain lion 10.8.4. Thanks heaps!
