Via “Perl.com”:http://www.perl.com I found “this post”:http://www.oreillynet.com/onlamp/blog/2006/08/make_your_vimrc_trivial_to_upd_1.html that has a tip for editing your .vimrc (as we discussed at “plug”:http://www.plug.org on Wednesday).
The basic hint is these two keybindings, which allow you to edit and reload your .vimrc, instead of trying to muck around with in the ex interface.
“,v brings up my .vimrc
“,V reloads it — making all changes active (have to save first)
map ,v :sp $VIMRC
