Zemismart Zigbee roller blind (border, click control, reverse direction)

I have a Zemismart Zigbee roller blind. HA control works fine, however, there are a few controls that I have no clue as to what they do. Can anyone shed some light?

They are…
border…with up, down, up_delete, down_delete, remove_top_bottom options
Click control…with up, down options
Reverse direction…with forward, back options
