 If you want to use a tap-hold with a keycode from a different code page, you have to define another behavior with another "bindings" parameter.For example, if you want to use SHIFT and volume up, define the bindings like `bindings = <&kp>, <&cp>;`. Only single-argument behaviors are supported at the moment.
 
 #### Note
-Astute readers may notice similarities between the possible behaviors in ZMK and other firmware, such as QMK. The hold-preferred flavor works similar to the `HOLD_ON_OTHER_KEY_PRESS` setting. The 'balanced' flavor is similar to the `PERMISSIVE_HOLD` setting, and the `tap-preferred` flavor is similar to `IGNORE_MOD_TAP_INTERRUPT`.

 For keyboards that require a (usually Pro Micro compatible) add-on board to operate, the ZMK integration pieces are places
 in the _shield_ definition for that keyboard, allowing users to
 swap in different Pro Micro compatible boards (e.g. Proton-C, or nice!nano) and build a firmware the matches their actual

 ## Shield Overlay

+ZMK uses the green color coded pin names to generate devicetree node references. For example, to refer to the node `D0` in the devicetree files, use `&pro_micro_d 0` or to refer to `A1`, use `&pro_micro_a 1`.

 The `<shield_name>.overlay` is the devicetree description of the keyboard shield that is merged with the primary board devicetree description before the build. For ZMK, this file at a minimum should include the [chosen]() node named `zmk,kscan` that references a KSCAN driver instance. For a simple 3x3 macropad matrix,
 this might look something like:
