Just the other night, I was with Love when she was clearing her gmail - *click* on the checkbox of the third (or so) email, scrolled hastily down (she's quite a speed reader), *shift-clicked* on the checkbox several rows down and the inbetween emails got their checkboxes selected as well.

"Eh? Wait! What did you do?.. Did you just hold the shift key?"
"Ya.."

In disbelief, I tried. It works. *gasp*. Shift-click. Like I've seen it the first time. I mean, I know it works on usual desktop stuff shift-click to select a range of stuff... but webpages / checkboxes isn't supposed to be capable of that.. I mean..

"Duh", Love rolled her eyes and continued to slaughter her inbox. Now, I'm dumb.
