Unintentional keystroke

Hello,

While writing some text, I made an unintentional keystroke that resulted in the line number presentation being on the right of the text instead of on the left, and the justification on the right.
Is there a key combination that would allow me to restore the default presentation or a way of “Undoing” this action?
Many thanks for your help.

I think you might have accidentally changed the writing direction to right to left. If so you can change it again by right-clicking on the note and changing the direction in the context menu.
