Over at the Google+ Emacs Community, Jean-Sébastien Ney (in a comment to this post) gives us a pointer to a very nice video on CUA-mode by Mark Mansour. Actually, the video really deals with the rectangle features of CUA-mode that we discussed recently. If, as I recommended, you put cua-selection-mode in your .emacs or init.el file, you can use all the tricks that Mansour demonstrates without having to invoke CUA-mode as he does.
Mansour shows how rectangle mode can do many of the things that Magnar Sveens wonderful multiple-cursors package does. The video is only 3 and a quarter minutes so it won’t take you long to watch it and it’s well worth the time.
