Expand folder contents shortcut?

Is there a keyboard equivalent of clicking on the arrow to the left to a folder in the binder?

I’ve searched the manual and the help system and the forums, and I can’t find an answer.

Thanks in advance.

You can use the Right and Left arrow keys to expand or collapse notes. Holding the Option key while pressing the arrow key will expand/collapse everything in the note, just like Option+click.

Exactly what I was after.

Many thanks.
