I would like to add custom columns to my library of nearly 1,000 ebooks. Is there any way to edit a new column other than selecting the specific cell twice with the mouse? It's a nightmare doing it like this.

I'd love to be able to edit a Y/N column by going into edit mode, typing Y, pressing enter (going to the next row), pressing some key to go back into edit mode, etc. I've attempted to do some searching for this answer but have had no luck. Any help would be much appreciated.

Thanks!
