How to disable Command-F1 toggle display

Yes can someone answer this other than to say "Select 'Use all F1, F2, etc. keys as standard functions keys'" ?

I don't want to do that, I want to disable one (1) (a single) keyboard shortcut that causes me nothing but frustration. I also use spaces and the command+# keys to go to a particular space. One fat finger slip and my whole setup blows up because apparenty some people need a built in unchangable option to turn mirroring on/off constantly.

Would like to bump this.

Apple seem to love irritating their users by implementing useless keyboard shortcuts that you can't turn off. Shift + any expose shortcut is another example of utter annoyance.

Use KeyRemap4Macbook (now known as Karabiner). It takes a while to learn how to use it, but it's very powerful. The following custom setting in private.xml works for me to simply disable this keyboard shortcut:

<item>

<name>Disable Mirroring Shortcut</name>

<identifier>private.disable_mirroring_shortcut</identifier>

<autogen>--ConsumerToKey-- ConsumerKeyCode::BRIGHTNESS_DOWN, VK_COMMAND, KeyCode::VK_NONE</autogen>

</item>

If you go to System Preferences > Keyboard > Keyboard, and check the box for "Use all F1, F2, etc. keys as standard function keys," then Command-F1 will no longer do mirroring. You'll then have to press Command-fn-F1 to do mirroring.

Explanation: The "special" functions of the function keys (i.e. setting volume, screen brightness, etc.) are not, themselves, changeable by the user. These keys have symbols for these functions directly on them, which tells you that Apple does not intend you to be able to change where those functions are mapped. It just so happens that turning mirroring on/off is treated as one of these functions; you're not actually pressing Command-F1 when you activate this; you're pressing Command-Brightness-Down. That's why setting F1 etc. to be standard function keys will now make Command-F1 actually be Command-F1, and therefore, it will solve all your woes in Photoshop etc.

I see it's still never been answered... in Photoshop I use command-1 all the time to zoom to 100%. If my finger slips upward just a bit I get surprised by the monitors going blue, then everything being duplicated.

To get back I hit command-1 again, and all my files and folders are tiny and stuck in monitor #1.

I haven't seen this in keyboard prefs.. so where is it? Or can someone at least say why this would be such a common feature that it needs a mandatory keyboard shortcut?

Yeah, this is brutally frustrating.

I saw a post somewhere about a setting a Keyboard Shortcut that does nothing, but as of OSX 10.6.8 that doesn't work - it ignores the keypress while the "Keyboard Shortcut" field is in focus.

Anyone??

I'm in the same boat. I want to use Cmd+F1 in Photoshop. But when I try to assign that short cut, Photoshop tells me that I can't use Cmd+F1 because it is used by the OS. I want to delete or set to None in the OSX 10.6 but I don't see any way to do this. system pref does not show Cmd F1 assigned anywhere.

Anyone else have any info on how to disable Cmd+F1 in the OS?

Is there a way to do this in Terminal?

Thanks

This doesn't solve your problem but I've printed out out a sheet of paper and stuck it next to my computer so that I can at least remember how to get it back without opening preferences again.

Has anyone found a solution? It's driving me insane.

Thanks

Still not answered? This is so agravating. I'm using a desktop, not a laptop. Cmd-F1 needs to be customizable! Sheesh Apple, fix this.

Bump!

Well here I am in Mountain Lion, and Cmd+F1 still can not be reassigned or set to none in the OS. I still need to use it in Photoshop :-((

I'm trying this in OS X 10.11, but it doesn't seem to work for me. The EventViewer shows no events for F1-F4 when those keys are pressed, which I'm guessing is part of the problem.

Hi! Maybe it is not too late. Make an action in Photoshop with cmd-F1. It is possible!
