Makes sense. I've now done this in Emacs 27, but while writing the code, it struck me that there has to be a ready-made function for this somewhere already. I had a peek through the plethora of switch-to/pop-to functions, but I didn't find anything that did exactly this... Does anybody know? In short: If there's a window that has the buffer, then that window should be selected, and its frame popped to the top (and given focus). If not, it should work like `switch-to-buffer'. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
