My fingers do Command-Option [1-4] for setting a header size. But this no longer works.
I have seen that you can now “just” use Command [1-4]. However; it is very much not satisfying because all other tools ™; or at least MS word, Atlassian confluence, and workflowy (another favourite) do respond to that combination.
With Bear 2 it now jumps to some other navigation point, and this is really disturbing.
