LinkThing is a Safari extension which enhances your control over how links on Web pages are opened.
Features - Have Safari open links in new tabs by default (when you just click them normally). You can apply this setting globally or per-site, and you can apply it to offsite links and onsite links independently. - Optionally open links in new tabs by right-clicking them. (You can still get the link's context menu by Control-clicking it.) - Choose where to position new tabs when Command-clicking links. - Instantly add links to your Instapaper account by using a context menu command. - Lightweight "pseudo status bar" option. Reveals the link URL in a small bar when you move the mouse over a link. You can hide Safari's status bar to save space without losing the ability to peek at link URLs.
