One Key - 1.2.1

I had been using (and getting addicted to) Function Key Mapper for several years and didn't know about One Key until it failed to work with Snow Leopard. I just thought I would give this a shot. This is superior in every way except one. One Key does not seem to have the ability to use modifier keystrokes to launch applications. So once you have assigned an Fkey to one application, that is all you can use it for. Try using a modifier and you get an error tone. Function Keys Mapper allows you to use modifiers.

However, One Key is much faster and doesn't use up any processor time to work properly (Function Keys Mapper always used up way too much percentage of the processors' time in my opinion).

I recommend it highly.

Currently, users of Apple branded laptops face the issue of having to press the fn key in order to use the function keys in a standard way (instead of with their default mode of adjusting brightness, etc). Many of us would prefer this, given applications like Flash, Photoshop, Quark and Apple's X11 & Final Cut Pro make extensive use of the function keys. Also, many of us rarely need to readjust brightness, etc compared to our use of application shortcuts. This becomes especially difficult when users switch between an Apple portable and a tower, and have to remember the extra keystroke for several shortcuts. Is One Key making any progress on inverting the fn key on PowerBooks & iBooks? Have developers noticed if Panther finally addresses this issue? A note to users: uControl came close with "Real Function Keys" feature, but they haven't yet been able to overcome the num lock hurdle, nor extend the real function keys beyond F1-F6. If your laptop boots into OS 9, there is a workaround you can find in your keyboard control panel, which, once set in OS 9 (not classic), will carry over when you reboot into OS X. Hopefully if third party key mapping utilities don't fix this, Apple itself will...
