with this-window default (or actually, the browser-default-default), I can middle click and it'll open in a new tab regardless

pretty funny to have this discussion though, takes me back to the HTML4 and XHTML days

I don't agree. If your design choice forces a user flow that is surprising, awkward, and redundant then it's definitely the wrong choice. It's still a call to be made by the design team, though.

Or just configure your browser to ignore the target param, eg browser.link.open_newwindow_restriction 0 in about:config

The fact I've gotten so many down votes for my previous comment really nails the point down how HN isn't really used by technical people anymore. It's mostly idiots with opinions.

i took ___ to mean the option key which has this symbol made up of lines: "⌥", it is also the key most likely to be used for such a feature, so i figured that's what you must be talking about.

if you weren't then the key most certainly doesn't exist on a mac either, and i apologize for the downvote. unfortunately it appears that i can't undo it anymore so i hope someone else will compensate with an upvote.
