Key Settings
Key Repeat Rate & No Combination With function keys
Short Cut For Typing
Keyboard Function Adjustment
Karabiner-Elements handle three features below:
**Replace Capslock With Esc**
[[Seil](https://pqrs.org/osx/karabiner/seil.html)]
Escape key means a lot to vim user, but the sad part is that escape key is pretty small and far from hand. Also capslock is the key which not using a lot, so it's make sense to replace it with escape key.
* Change the capslock key: 51 => 53
**Exchange Command/Option Key**
[[Karabiner](https://pqrs.org/osx/karabiner/)]
This trick is useful for mac user want to use external keyboard. Just need to exchange option key with command key, and also the opposite.
Check all these options：
* Change Command_L to Option_L: 55 => 58
* Change Command_R to Option R: 54 => 61
* Change Option_L to Command_L: 58 => 55
* Change Option_R to Command_R: 61 => 54
**Map Function Keys**
When using external keyboard for mac device, you must map function keys so that you can perfectly trigger these function.
1. Change F1-F19 key & functional key
2. For PC Keyboards
3. Check the first option with "You can use standard function key fn-f1.....fn-f12".
