right… i know about the fn key and the system pref which reverses the behavior (F keys work as F keys and you have to use the fn key to use the volumes/pause/expose features printed on the F keys)…
i guess the problem is most (by far?) mac users are using the F keys as the defualt setting and that using the fn key is a two handed operation for many of the keys (unless you have a seriously big hand )
i’m a keyboard guy too and generally only use icons for less used tools… but for me personally (and this goes for all apps) i always use keystrokes which don’t involve F keys… and very few applications (i know photoshop has a few) will have settings tied to F keys.
anyways… i didn’t mean to say F keys are simply non-existent on mac… just that nobody (in general) uses them- developers or users… they’re way more used as the osx defaults of hardware and OS controls
