navigation pane size

I seem to have made the navigation pane full width and cannot fathom how to revert it back to a narrow pane on the LHS.
How do I do it, please.

Hello

not sure, if I got you right, but click the icon with the three stacked dots (right upper corner) and click item Dock

Hope that helps.

Thanks for the prompt response - much appreciated.
I do not have the 3 -dots!
RH Styles sidebar has them but now that the nav sidebar is full width, the dots have gone.
Trying to drag RH edge just pulls Styles sidebar over.
Tried closing app and restarting but still no dots.

Please avoid acronyms (I don’t understand what you mean by LHS and RH). If that doesn’t help reset your user profile by starting LiobreOffice’s Safe Mode.

Apologies: LHS = Left Hand Side RH = Right Hand
I have now posted a solution to my question which I hope may help others too.
Thanks for the suggestions.

I have found the answer from a similar question on the forum:
CTRL-Double-Click on the pane and it reverts.
