In Composition Mode, select text, hit Ctrl-K and… nothing happens. Works as expected outside Composition Mode, which turns the writing of newsletters a game of enter-exit-enter Composition Mode.
According to Scrivener I am running the latest version.
I can confirm this behavior on Scrivener v3, but for me Ctrl-L is the Add Link shortcut. (It’s possible that at some point I changed the shortcut. ) Edit Link Ctrl-Shift-L also doesn’t work in Comp mode.
Check for updates only confirms whether you are at the latest update within a particular version, which doesn’t tell us whether you’re on v1 or v3.
I’m experiencing this bug on v3.1.1.0, so I assume that’s what you’re on as well, but could you please confirm your version using Help > About.
