Seemingly redundant and/or confusing default mappings

Hey folks,

I've been using Mutt so far for 8 months.  My favourite thing is its
customizability.  I do, however have an inquiry -- "Why do navigation keys for
the index differ from those of the pager?"

For instance, to navigate to the top of the *index*, I'd press =, but to
navigate to the top of the *pager* I'd have to press ^.

If I wanted to navigate to the bottom of the *index*, I'd press *, but to
navigate to the bottom of the *pager*, I'd have to press <End>. I'd also like
to point out that when in the pager, the * key is unbound so (as far as I
understand) there would be no key conflict in making the keys the same.

TYIA.
