Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

These links no longer work. Springer have pulled the free plug.

Using the latest Chrome Beta (11.0.696.16 beta) and the new HTML5 Speech Input features, we can jump into the future with Wolfram|Alpha.

Make a bookmark with the code below as the source.

javascript:(function(){javascript:input=$('input');
['','webkit','x-webkit-'].map(function(prefix){input.attr(prefix+'speech','').bind(prefix+'speechchange',
function(e){$('form:first').submit()})})})();

Navigate to Wolfram|Alpha, click the bookmark.
