At least for the first two, might I suggest mapping the commands vim uses for navigation? If you run :help tags, it will give more information.
Basically, CTRL+ ] navigates to the item under the cursor (so, navigating to a link), while CTRL + O goes back, and CTRL + I goes forward.
It’s not default mappings, but if you set this up, it will be consistent with how Vim behaves normally.
