 Your keymap can include shortcuts to common operations (called "function actions" in tmk).
 
-These functions work the same way that their `ACTION_*` functions do - they're just quick aliases. To dig into all of the tmk `ACTION_*` functions, please see the [TMK documentation](https://github.com/qmk/qmk_firmware/blob/master/doc/keymap.md#2-action).
+These functions work the same way that their `ACTION_*` functions do - they're just quick aliases. To dig into all of the tmk `ACTION_*` functions, please see the [C macros for action code](https://github.com/qmk/qmk_firmware/wiki#c-macros-for-action-code).
 
 Instead of using `FNx` when defining `ACTION_*` functions, you can use `F(x)` - the benefit here is being able to use more than 32 function actions (up to 4096), if you happen to need them.
