我使用苹果的无线键盘,一开始也碰到了相同的问题,后来在论坛上找到了答案,照着做了就ok了。
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).
