RE: select yank via completion

FWIW, Icicles uses `icicle-completing-yank' for `M-y'
not right after `C-y'.  It's also bound to `C-- C-y'.
(`C-y' is `icicle-yank-maybe-completing'.)

| 
| (icicle-completing-yank)
| 
| Yank an entry from a selection ring, choosing it using completion.
| By default, the selection ring used is the kill ring.
| 
| If you also use library `browse-kill-ring+.el' or library

Actually, if you use library `second-sel.el' then, by
default Icicles binds `M-y' at top level to command
`icicle-yank-pop-commands', which lets you choose a
selection from either kll-ring or secondary selection
ring, using completion against the ring entries.

,----
| icicle-yank-pop-commands is an interactive compiled Lisp function in
| 'icicles-cmd1.el'.
| 
| It is bound to M-insert, M-y.
| 
| (icicle-yank-pop-commands &optional ARG)
| 
| `yank-pop', `yank-pop-secondary', or `icicle-completing-yank'.
| Which of these is used depends on the previous command, as follows:
| 
|  * If the previous command was a yank-secondary command, then
|    `yank-pop-secondary'.
| 
|  * Else if the previous command was a yank command (i.e. using the
|    kill ring), then `yank-pop'.
| 
|  * Else `icicle-completing-yank'.
| 
| In the last case (`icicle-completing-yank'), during completion you can
| use:
| 
|  * `C-,' to sort the candidates to yank in different ways (repeat)
|  * `S-delete' to remove a candidate entry from the selection ring
|  * `C-S-return' to copy a candidate to the other selection ring
| 
| You need library `second-sel.el' for this command.
