+Large screen, lots of windows, so where is the cursor? While I used to use =hl-line+=, I found that the prolific [[https://protesilaos.com/][Protesilaos Stavrou]] [[https://protesilaos.com/codelog/2022-03-14-emacs-pulsar-demo/][introduced his Pulsar project]] is just what I need. Specifically, I might /loose the cursor/ and need to have it highlighted (using ~F6~), but also, this automatically highlights the cursor line with specific /actions/ , like changing windows.
