How do V-series Mirrored keys work?

On the V-series panels (using EHX v9 or later), you can assign the same key to multiple shift pages and they all act as one single key.

Latching a key on the main page will also mean the same key on shift page 2 will also be latched on.

This allows the operator to always have access to their important keys on all pages and the keys will stay in sync in terms of key press and xpt level.

Note:
There is a max mirrored key allowed per panel.
i.e. one can have 16 keys to group 1, 16 keys to PL 10 etc all at the same time.
