I've only owned Apples but the function keys all have duel purpose. The F1-18 keys do things like cut, copy & paste, print, zoom in/out, etc. I guess I'm not sure of the difference you're asking about bw function keys and Apple function keys.
Thanks for the quick response.
I purchased a BTKEY unit from another sotre only to find out there are 2 models. The older one (which I am looking for) does not have Function keys dedicated to Apple functions, which I what I want. The picture in your ad appears to show function keys with only numbers (F1, F2, F3 etc.) and the volume keys appear to be on the far upper right of the keyboard. Can you verify if that is the keyboards you ship have these simple F keys or if they have icons Apple functions on F-1 through F18?
