Quick filter

[mgigli]

Hi,
Since I started migrating from TC, I have been trying to migrate some functionality to which I had become accustomed. I have already migrated TeraCopy and was searching for other things. The last thing I'm trying to configure is the quick search.
In TC, the quick search option allows you to only show files that meet the criteria. Here, Quick Search doesn't have this option, but Quick Filter may serve the same purpose. However, I can't figure out how to close or delete the Quick Filter option. I don't know if there is a missing keyboard assignment that I can't see. I'm trying to accomplish this with a user-defined internal command, but I also can't find any command that quickly closes (cleans, erases, etc.) the quick filter.

Ctrl+F for the Filter Box focus then Backspace to erase & Escape to return to the main view.

I know it's a bit of a hassle, but is there any way to do this with a single key? For example, by using an internal command that I assign to a key?
