[My screen turned black and my toolbars are gone. Can this be undone?]

Thanks so much!  That brought it back.

[My screen turned black and my toolbars are gone. Can this be undone?]

My daughter pushed caps lock (and possibly something else) on my Mac while I was working in Affinity designer, and immediately all my toolbars went away.  Now I just have a black screen with the white design area showing.  Is there a way to get my toolbars back?
