a semi transparent brightness control box would appear

but these buttons no longer do anything
and the box doesn't appear

Click to expand...

try pressing the fn key while pressing f1 and f2
 
have I gone mad
is it possible I didn't need to do that before

that works
 
System Preferences >Keyboard and Mouse > Keyboard tab > uncheck use all F1 and F2 as standard function keys. HTH.
 
Thanks - thats better

I may have accidentally checked that
as I was roaming around there recently
 
yes thank you!

I'm sitting here trying to raise the volume and f@#&ing dashboard keeps coming up.
😱
 
I can't adjust brighness or volume using F.keys!

Hi

I am no longer able to adjust the brightness or volume or activate the numlock using the F-keys.
I have tried the Sys. prefs. > keyboard and mouse > keyboard > Use all F1, F2, ... and then trying the F-keys using fn, but no effect!

F10, F11 and F12 e.g. is working fine.

I have a wireless mac keyboard where the F-keys are working. The difference on the two keyboards is that, the wireless is the newest keyboard version.

I am able to adjust the brightness by using the 'display prefs' and volume I can adjust by using the slider for controlling the volume.

I am running mac os x leopard.

Do you have any ideas of how to solve this problem?

Thanks!

😕
 
oh gosh thank you so much. I just made a post about this. I was sooooo annoyed by the keymaps seeming different than what is printed on the keys!
 
I used to be able to adjust the brightness with F5 & F6 but now for some reason it doesn't function? When pressing F5 or F6 a semi transparent brightness control box appears and nothing happens with the actual brightness even though the marker increases and decreases.

I can adjust the brightness from system preferences/displays.
And I don't have the function keys ticked in the option.

Any help with this much appreciated. This is so frustrating, why suddenly it doesn't function?

Oh, and it's a 15" Unibody MacBook Pro.
