Use the patch from the attachment for ELinks-0.12.GIT. I hope it works as
expected.
I have no write permission to the main branch, so you must ask someone to
commit it.

viewer: Added new four actions requested by Ligesh.
move-link-down-line moves the cursor down to the line with a link.
move-link-up-line moves the cursor up to the line with a link.
move-link-prev-line moves to the previous link horizontally.
move-link-next-line moves to the next link horizontally.
