For the hyperlinks, it seems editing the text and visiting the link is easy. But there isn’t a way to edit the hyperlink itself quickly?
Have you considered using affinity cursor along the up/down for that as well? Eg. Up updates the hyperlink content while default/down updates the link text.
Not sure how it would work out UX wise. Maybe opens up a popover with cursor for the hyperlink.
Correct. For that you need to use Formatting pallet (also in video). I did initially build it so clicking link would open a pallet with option to follow link or edit link (Pages.app) does that. But in the end felt better to make following link fast and add/edit links slower.
Up/Down could work, but I think it would break text editing movement/consistency more than I would want. For example if you were down arrowing to navigate you document and then randomly hit a link it would be frustrating to see link editor instead of keep moving down.
