It should suffice to rename .vimperatorrc to .pentadactylrc and
.vimperator to .pentadactyl
>Secondly, is there somewhere an explanation about why one should leave
>vimperator / muttator in favor off pentadactyl / teledactyl?
I wouldn't recommend leaving Muttator for Teledactyl at the
moment. As for Pentadactyl, it's mostly a matter of whether you
prefer the changes in the changelog to those in Vimperator. I
will add, though, that the most active developers of Vimperator
for the past 4 years, even considering the past months of
inactivity, have been Doug and I, both of whom are now working
on Pentadactyl rather than Vimperator.
The power of instruction is seldom of much efficacy except in those
happy dispositions where it is almost superfluous.
