 ## Keymap
 
 As the 60% keyboard lacks a lot of keys such as F1~F12 and arrow keys, <kbd>Fn</kbd> is used to activate a new layer.
-When holding <kbd>Fn</kbd> down, the following keys are activated.
+
+By default, holding <kbd>Fn</kbd> down activates the following functions:

+Except for <kbd>Fn</kbd>, any normal key can be used as a Tap-key. A Tap-key is a key that can be used as an ordinary key when tapped, or can be held down to activate alternate functions.

 ## Using Pair-keys

-By default, <kbd>J</kbd> <kbd>K</kbd> are used as a pair-keys. When simultaneously pressing <kbd>J</kbd> and <kbd>K</kbd> in a text editor, it will output a pre-defined string.

+Two sets of pair-keys are configured by default, to illustrate how to set up these keys. These include <kbd>J</kbd> <kbd>K</kbd> and <kbd>U</kbd> <kbd>I</kbd>.
