[chimerax-users] Graphical Window

Hi all, I hope you are doing well. If I hover my mouse over a structure in the graphical window of chimeraX, a short text is loaded revealing information about the residue/atom/bond my mouse is hovering on. I want to take advantage of this feature, but I want to perform a task different from the default one but still specific to the part of the structure my mouse is hovering on. As of now, I don't really know how to go about this and I am trying to locate the scripts that encode the original feature just so I can get an idea of how to go about this. Could you please help locate those scripts (if possible)? Regards, Shubham
