Copy this to a new bookmark. I named mine "Send to Phone." It pops up a little window with the URL of your current web page encoded as a QR code. Simply scan it directly off your computer screen with your phone's QR code reader and off you go! (I don't claim credit for this bookmarklet; I found it at http://www.masukomi.org/projects/qr_bookmarklet/.)
