M-x list-faces-display RET > 2. TAB TAB RET C-x o (but see below*) ^ Missing a C-x o here in the original recipe. So I doubt this is directly related, but I'm noticing another peculiarity regarding help buffers not named `*Help*'. As you'd expect, going back via a back button replaces the window buffer with the previous one. And though typing "l" does that as well, it also re-creates the previous buffer in a new window, resulting in different buffers with the same content (the new one being the default "*Help*"). >From emacs -Q (on Emacs 30): 1. M-x list-faces-display RET 2. C-x o TAB TAB RET 3. In the help buffer for `abbrev-table-name': RET 4. In the help buffer for `font-lock-function-name-face': RET 5. Back in `abbrev-table-name': TAB RET (should take you back to "*Faces*") Now start a new session, repeating 1-3. For 4, hit "l" instead, and witness the unwanted default "*Help*" buffer pop up in another window. Superficially, I think the disparity results from `help-xref-following' being t in the base recipe (at the hands of `help-do-xref'): * help-xref-go-back(#) help-do-xref(nil help-xref-go-back (#)) help-button-action(#) button-activate(# nil) push-button(751) Which allows for buffer reuse in `help-buffer'. No such arrangement occurs with the "l" variant: * help-xref-go-back(#) help-go-back() funcall-interactively(help-go-back)
