Is there an "Undo" button?

Is there a quick way to undo the last command entered? Like the “Undo” button on MS Word?

You can use the shortcut cmd+z or click on the option undo in the popup window

and in case you are on mobile you can use the toolbar

The current pop-up no longer has Undo.

You are still able to use Ctrl + Z

Thank you. And Ctrl + Y to reverse the undo (redo?), in case I go overboard!

ctrl+shift+z also works to redo.

Well, I didn’t know that! I will have to add that to my remnote “how to” notes and study that until it’s internalized! Thank you!
