Hi Here we see a list of keyboard shortcuts for Evernote for Mac.
Each note can have a URL associated with it, visible in its Note Info, then you can click on "View Site" to open that URL.
I think it would be useful if that primary hyperlink could also be opened by using a keyboard shortcut when focused on the note in a list view or (particularly) when editing it.
I ran a check and couldn't see this having been discussed or implemented yet.
