made for the delete operator with these movement commands: |%|, |(|, |)|, |`|,
|/|, |?|, |n|, |N|, |{| and |}|. Register "1 is always used then (this is Vi
compatible). The "- register is used as well if the delete is within a line.
+ Note that these characters may be mapped. E.g. |%| is mapped by the matchit
+ plugin.
With each successive deletion or change, Vim shifts the previous contents
of register 1 into register 2, 2 into 3, and so forth, losing the previous
contents of register 9.

+ let @# = altbuf
