This is probably one of those "You use vim and don't know how to do

but then would like to search for that text.
You're close. You can use control+R followed by the register-name to
insert that register at the search prompt. So you can do something
like
/<C-R>b
to insert the content of the "b" register at the search prompt.
Sweet! That's exactly what I'm looking for. I didn't know about ctrl-R,
that seems like it will be generally useful.
Note
that this is interpreted as a regular expression, so if your register
contains regex metacharacters, you'd have to escape them. Which can
be done from a mapping with something like
:cnoremap <f4> <C-R>=escape(@b, '.\*/')<cr>
where the ".\*/" is a list of characters to escape.
Yes, I'd expect it to be treated as a regex. Thanks for the mapping
though, I'll definitely use that.
You can read up more at
:help c_CTRL-R
:help @=
:help escape()
if you want the ugly details.
I like ugly details :-), I just couldn't find them in this case.
"ctrl-r" doesn't appear in :help /, or :help register. It does in :help
search, but I don't think in a way that would have told me what I
needed, even if I did know I needed ctrl-R. On the plus side,
cmdline.txt (which is where :help c_CTRL-R takes you), looks quite
useful, I'll have to read the whole file.
Thanks!
Brian
