If I am holding down backspace to delete several words, if I hold it down for more than about a second, it will delete everything until the beginning of the line. I would rather it just keep deleting words at a constant pace. I feel like I am working around this "feature" more often than I am using it, ie, I want to delete everything except the first word on a line, and I end up holding backspace for just under a second, waiting, holding it again, waiting, holding again, etc.
The most common occurance is when I want to delete everything after a slash in a web address.
