Possible bug: on my system, although Ctrl-[ and Ctrl-] move up- and down-by-paragraph, I'd expect that holding down the Shift key with them would allow me to select paragraphs-at-a-time, but it doesn't work. I've tried it with all combinations of both Shift and Ctrl keys but no joy.
(Caveat: I'm using a kinda' fancy programmable keyboard, using the dvorak layout, but that's never been an issue in the past.)
