I'm not used to using Penpa, and sometimes I wonder if there are shortcuts that I'm not aware of that would make it easier to use.
For example, if I make a mistake is it possible to 'Undo' the last move or two?
If I want to try something that I'm not sure about, is the best way to click the Clone button or are there any other options?
(or let me know if there is a Penpa info page or forum thread I should go to)
