Edit; offtopic/closed but if anyone has the same question, below could help but is an article from 2018;
https://support.apollo13.eu/discussion/5677/how-to-change-the-hover-text-with-the-hidden-sidebar-icon-in-peeky

I appoligize if this question has been answered before, I googled and didn’t find an answer.
In the top right of my wordpress page, I have a button that opens a hidden sidebar. When you hover over that button with the mouse it shows “More info”. I want to change this text to “open sidebar”.

However I cannot seem to figure out where the setting for this is in the GUI. I can change it in “inspect element” but that’s about it.

I’m using Rife theme, probably there is a setting somewhere but I cannot find it.
If anyone can point me in the right direction I’d be grateful!
