The short answer is no.
Various skills are only able to be seen by some classes, much in the way that cabal skills can only be seen by that (sub)cabal.
For example, if you were a berserker, you couldn't pull up the warrior lore help file for backcutter as you're obviously not a warrior. Likewise, warriors can't bring up berserker lore help files.
Age can't be seen by Mysterium.
So you're not going to get into the nitty gritty of some help files.
There's an exception to this with a Sigil skill. But that's for the prayer forum and hopefully it's been corrected.
Of course, Imms get access to (almost) all the help files.
