The link given on Adobe web site
does not work !
Does anybody have this manual (in french).
This appears to be the link involved.
But, at first glass, it appears to offer active 13 and 12 Help PDF. The choice for 11 does not work for me, although 12 and 13 do. For version 11, I get page not available. For the rest, many may display after a short delay.
If you have Premiere Elements 11, have you tried to access its Help PDF from its Help Menu within the project?
Please consider and supply more information.
