Is there a way to recover your quick collection if you accidentally cleared it? I store a lot of photos I'm currently working on within my Quick Collection, but I mistakenly hit the hot key I think and I've done too many actions since hitting it and can no longer just Undo to get it back. PLEASElet me know if you have a fix
The keyboard shortcut to Clear the Quick Collection is Ctrl + Shift + B which is a very Odd combo of keys.
So unless you somehow hit all those keys at the same time, by Accident, I doubt it was that shortcut that removed all images from the Quick Collection. Also that only works for the actual Quick Collection entry in the Catalog section of the Library module. If you set some other collection, Any other Collection, as the Target collection that keyboard shortcut does nothing.
