The BlackBerry Z10 has a pretty sweet virtual keyboard. When you have a good flow you can really bang words out.
But what about when you make those silly mistakes?
One of the things you can do is place your finger on the keyboard and slide it to the left. This deletes the whole previous word. It's pretty cool, and makes deleting text a doddle. What's a little less known though, is that you can delete more words in a single swipe simply by placing more fingers and thumbs on the keyboard.
