I wrote some JS to add keyboard controls to the map, because clicking and dragging is for suckers. http://www.potch.me/blog/press-and-hold.html
javascript:var kn=document.createElement('script');kn.src='//raw.github.com/gist/3748621/1bbdaee115134d0106978e42a5423f7b3e5de5e3/nav.js'; kn.type='text/javascript';document.getElementsByTagName('head')[0].appendChild(kn);I added a bookmarklet of the original code to the site- I know you're legit, but I'm always wary of encouraging people to load random external JS via a bookmarklet.
EDIT: The mouse does move off the view port during drag, so its probably not that much more efficient.
Ah well, it was a momentary amusement. :)
