Hi, since I switched to Mac, i really have problems with the Apple keyboard. I mean, its great for a short use, but for me, when I need to write something precise without many typos, I cant do it with that. So I tried my previous PC keyboard, a Ducky. Works fine, the only issue i have is that there is no EJECT key and when I want to lock my screen, it was that very nice and easy 3-key combo that i could use on Mac keyboard. But again , since there is no eject key on a non-apple keyboard, is there a way to make that work somehow ? When I googled, I read that F12 might work too, but it doesnt. Any other way to do it ? I would appreciate any help.
