If you’re using an Apple keyboard with Linux and want to use the Function keys normally, for example F2 to rename files, it’s possible to do so with a simple modification.
Open a terminal and run this command:
sudo -s 'echo 2 > /sys/module/hid_apple/parameters/fnmode'
If you want something other than Function keys taking precedence there are other options.
The following are the accepted values:
- 0 = disabled : Disable the ‘fn’ key. Pressing ‘fn’+’F8’ will behave like you only press ‘F8’
- 1 = fkeyslast : Function keys are used as last key. Pressing ‘F8’ key will act as a special key. Pressing ‘fn’+’F8’ will behave like a F8.
- 2 = fkeysfirst : Function keys are used as first key. Pressing ‘F8’ key will behave like a F8. Pressing ‘fn’+’F8’ will act as special key (play/pause)
