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.

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.
