    How to disable default Fn shortcut keys for an app


    I have an app called Far manager where you need to press Fn + 4 key to edit a file, and when I used it my laptop went to sleep. How do I disable this behavior in Windows and "customize" the shortcut keys?

    :)
     

  2. FN key always on

    Are you sure it is not a mechanical issue with the key's switch?

    Check also the notebook's "Accessibility" features. These make the Fn key a "sticky" key so folks with disabilities don't have to press the Fn key and another key simultaneously. This may be in the BIOS but it may also be in notebook's own software that loads at boot. And the OS itself will have some "accessibility" functions. On my Toshiba, the default is for the "Sticky Fn" key to automatically unstick after a couple seconds but there is an option in the menu to disable the automatic unstick feature - meaning it stays "pressed" indefinitely.

    Last, if this notebook's OS has been updated, you might check the notebook's webpage for driver updates.
     
  3. FN key always on

    To clarify, I was saying "Accessibility" features maybe be controlled via the BIOS, not the Fn keys. And one of the Accessibility features makes the keys "sticky". This allows folks with some disabilities to press, for example, the Ctrl key, then the Alt key, and then Del in sequence instead of all at once. Same with the Fn key. The sticky feature would let you first press the Fn key, and then the F9 key (for example) and not Fn + F9 at the same time to enable/disable whatever Fn + F9 does with that notebook (it is the touchpad on my Toshiba).

    FN key always on

    A friend of mine daughter has an Asus Transform book that I'm interested in buying. There's only one problem: the FN key is always active. Pressing the key does not turn it off. I went into to BIOS to see if it can be disabled in the but there's no option. Is there a way to disable the key from Windows? Like a registry hack or something? It's something that I want, but the FN key is driving me crazy!
