As it turns out, you can include ANSI escape sequences in 
VF-1's bookmark files. I won't bother explaining how to do 
that, as the informaiton is readily available. I just wanted 
to say it works.

I will add, in case you're not familiar with it, that you 
can easily insert the escape character in vi with a literal 
insert: enter insert mode and hit C-v and then hit the esc 
key. You can also easily insert the character in nano by 
pressing M-v and then esc... if you use xterm, you may have 
to ctrl+leftclick and uncheck modifiers, check "meta sends 
escape", or change things in your xterm config file. I'm 
sure there are ways to do it in just about any editor.
