Saving Rectangles in Registers
A register can contain a rectangle instead of linear text. The
rectangle is represented as a list of strings. See Rectangles, for
basic information on how to specify a rectangle in the buffer.
- C-x r r r
- Copy the region-rectangle into register r
(
copy-rectangle-to-register). With numeric argument, delete it as
well.
- C-x r i r
- Insert the rectangle stored in register r (if it contains a
rectangle) (
insert-register).
The C-x r i r command inserts a text string if the
register contains one, and inserts a rectangle if the register contains
one.
See also the command sort-columns, which you can think of
as sorting a rectangle. See Sorting.
