I love Google Images search capabilities. For me, the ability to drag and drop an image and get back information is a killer app.
Anyway, Lifehacker just showed me a cool hotkey for Chrome. If you see and image on a webpage, and want to know more about it, hold down the S key, and then right click. This feeds the image to Google Images which then automatically searches for it.
I’ve been slowly shifting from Firefox to Chrome over the last few years. This tip is probably the tipping point for me.
