DESCRIPTION
Swapping text areas when there's other text in between (e.g. function
arguments separated by other arguments) is done frequently, yet cumbersome.
One way to do this is by deleting A, selecting B, pasting over it, then going
back to where A used to be and pasting the original B.

This plugin lets you exchange the current selection / line / text covered by a
motion with the previously deleted text, with a short and simple mapping. The
swap can be undone as a single action.

SOURCE
Based on vimtip #470: Map to quickly swap/exchange arbitrary text by Piet
Delport and an enhancement by ad_scriven@postmaster.co.uk.

SEE ALSO
- The LineJuggler.vim plugin (vimscript #4140) provides [E / ]E mappings to
  swap lines / the selection with the same amount of visible lines located
  [count] above / below.
- The LineJugglerCommands.vim plugin (vimscript #4465) provides swapping of
  ranges as an Ex :Swap command.

RELATED WORKS
- visswap.vim (http://www.drchip.org/astronaut/vim/vbafiles/visswap.vba.gz)
  uses a visual selection, <C-y>, another selection, <C-x> to swap the two.
- swapstrings.vim (http://www.drchip.org/astronaut/vim/#SWAPSTRINGS) can swap
  all instances of two strings in a range.
- swap.vim (vimscript #3250) can swap around a pivot (e.g. ==) or to WORDs to
  the left / right with <Leader>x / <Leader>X.
- exchange (https://github.com/tommcdo/vim-exchange) defines a cx{motion}
  operator that has to be used twice to exchange the first with the second
  one.

USAGE
First, delete some text (using any normal Vim command, such as "daw",
{Visual}x, or "dt"). Then, visually select some other text, and press
<Leader>x, or use the custom operator <Leader>x{motion}. The two pieces of
text should now be swapped.

{Visual}<Leader>x       Swap the visual selection with the just deleted text.
<Leader>x{motion}       Swap the characters covered by {motion} with the just
                        deleted text.
[count]<Leader>xx       Swap the current [count] line(s) with the just deleted
                        text.
[count]<Leader>X        Swap the characters under the cursor until the end of
                        the line and [count]-1 more lines with the just
                        deleted text.
