There’s a facebook group called “I will type telegraph style to end run-on typing STOP” owned by my friend Mike.
I kinda like the idea, so I created a (very crude) bookmarklet to make our lives easier:
Simply drag the link to your bookmarks bar, select text and press it, the selection will be updated in telegraph style.
The bookmarklet works in Firefox, Safari and Chrome. I don’t know if it works in IE, and quite frankly, I don’t care.
