FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
| Change Function Key behavior | |
| This section of the document describe how to change the behavior of 'fn' key to better match what user expect. (See #201711, #162083) | |
| Here a description of each behavior : | |
| 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). | |
