[Orgmode] Yanking the descriptive part of a link

[Bastien]

Hi list,

i came accross this situation several times: i have a (long) link in an
org-mode buffer and want to label it by yanking some text.

My first move was to select the link as the region and try C-u C-c C-l on
it, since org-insert-link does just the opposite : it takes the region as
the default label for some link you want to yank.

But the universal argument of C-c C-l makes org-insert-link deal with file
names.

Does anybody know any automated way to yank text as the descriptive-part of
an org-mode link ?

Thanks !
