Best to visit the iClone5 online documentation and look at the Animation and Timeline sections (and the subsections of those sections).  That'll give some idea of what's possible.  There's so much stuff though, so even in the other sections you will find animation related stuff.

I'm not sure I'm allowed to link to it, so I won't, but I recommend reading the online documentation if you want an idea of how powerful it is and how it differs from Poser.
