Answer 1

Another slight similarity: In Emacs, the rectangle editing features provided by cua-selection-mode (or cua-mode) automatically gives you multiple insertion points down the left or right edge of the marked rectangle, so that you can type a common prefix or suffix to all of those lines.

e.g.:
M-x cua-selection-mode RET (enable the global minor mode, if you don't already use this or cua-mode)
C-RET down down down (marks a 1x3 character rectangle)
type prefix here
C-RET (unmark the rectangle to return to normal editing)
