How to delete multiphe keys when switching to manual track?

Hi team. Pushing further this marvellous tool, let’s say I want to delete all keys inside my red quad selections. Is there a way to do that ?

Yes, go into the dope sheet and delete the keys for the track. Boris FX | Mocha® 2021 User Guide

You can also manually delete keyframes one by one in manual track using the keyframing tools on the righthand side of the playhead but that’s an unappealing process. Use the dope sheet instead.
