Selecting Multiple Lines of Text in CC Using Shift

Just upgraded from Dw CS6 to CC. I used to select a group of text by clicking a line number, holding shift and then clicking another line number but this doesn't seem to be working in CC. I can't find in the MissingManual that this is a feature in CC either. Is this a feature they have removed? Such shame if so! You'd think it doesn't matte as you can drag the mouse still to select multiple lines of text, however the shift-only method is very handy when highlighting a specific line and the scrolling down over a page (or more) and then accurately selecting the next line.

I quite like to set my own shortcuts for Dw. If this is a removed feature, is it available to create a shortcut for it? I've had a look but can't seem to see where this would be possible either.

Thanks!
