Is it possible to do multi-line editing like Sublime Text but in Vim? I use both, and this was the feature that got me out of Terminal, but besides this I can't think of anything else offhand for what ST2 can do that Vim can't do.
See: http://vimdoc.sourceforge.net/htmldoc/visual.html#blockwise-...
ST2 allows multiple cursors in arbitrary locations - I'm not aware of another editor that supports that.
Switches case on lines 4, 15:
:4,15 norm ~
Indents text and changes the first two words of ever line to "duck" from mark a to the end of the file
:'a,$ norm >>2cwduck
Prepends a # to every line of the visual selection
:'<'> norm I#
Applies regex to lines that match a regex
:g/ducks/ s/moo/quack
