Hi Vincent,

I believe the icon or keyboard shortcut that brings you to the end of a beamer presentation will also unfold all fold'ed environments.

1) i have searched in all the help manual, not found anything relative to "fold/unfold" ("plier/déplier")

but by right clicking in a field environment, i got the help page

maybe i read wrong but in this help page i did not found anything relative to how to (un)fold all the "fold" environment ; is there a means to do that ?
