In the Agenda 11 beta (and as far as I can remember also in previous versions) it is hard or maybe even impossible to link to another note quickly via the keyboard.
If I select some text and hit ⌘K, the link destination window opens but it is only possible to insert a link.
What I’d like, as a feature request, is an autocomplete field that searches through my notes and gives me the headings + metadata of the notes. Alternatively, I could paste a URL into the textbook and that would also be a valid input.
With the mouse, this is already possible quite easily by right clicking on the selected text -> Link To. It would be great to have those options easily keyboard accessible, too, to avoid the need of putting the hands off the keyboard.
