Locking Feature

Okay Im might be bit dumb dumb, but if I lock a block and want to unlock it. Do I seriously have to go to the explorer and look for the specific block to unlock it? No offense quite annoying. Any Help would be appreciated thanks

Enable the lock tool, then in the viewport simply click on the locked object to unlock it, alternatively you can click the little drop down and do “Unlock all” if you don’t have anything else you wish to keep locked.
