I would recommend something other than mapping jj to Esc (e.g. external
to Vim, map CapsLock to Esc), but to each his own.

Not in the general case, no. Vim running under a terminal doesn't
necessarily have a way to detect that you're copy-pasting (rather than
typing).

One thing that makes this easier is the 'pastetoggle' option (short=
'pt'). It allows you to assign a key to put you in 'paste' mode (where
lots of options are turned off).

See:

:help 'paste'
:help 'pastetoggle'
