Text object that allows you to specify range directly!
For introduction to text objects, see :h 4.8.
Press y, you're in the Operator-pending mode now, press : for a Range text
object and specify some range (all the usual shortcuts like % and 1,$
work), press enter, you yanked the lines in range! Ok, not impressive, I see.
Here's another one. You have vim-commentary (or an alternative) installed. This
gives you a gc operator. Press gc, you're once again in the
Operator-pending mode, press :, select some lines (ANY lines!), press enter,
now these lines are commented!
