Oh, I agree -- I usually like the context, myself. However, mpage is
treating buffers rather like a book with two (or more) pages visible at
one time -- and so I'd like ctrl-f and ctrl-b to move a whole page
forwards/backwards. I've built in the noremaps (one example shown) but
I wanted some reassurance that it was a common effect. So, thank you
for the quick feedback!
