backward-dir/forward-dir

[David Kulp]

Is there a key binding that allows me to move forward or back to the  
next slash in a file path?

In emacs shell mode, M-b and M-f will move the cursor to the next  
level of a /long/path/to/file.
In zsh, M-b and M-f jump over the entire path.  But I usually want to  
make a small edit in an existing path.

Strangely, I have noticed that ":" also serves as a word delimiter,  
so M-b or M-f will stop on the colon for host:/path.  So that  
suggests to me that there's a set of word delimiters defined somewhere?

Thanks in advance.

Actually, it's the other way round: the WORDCHARS parameter specifies which 
characters (in addition to alphanumeric characters) are considered part of 
words. It contains several characters that make sense by default, so I think 
your best course of action would be to just exclude slashes:

WORDCHARS=${WORDCHARS//\/}

Yes, it's in the parameter WORDCHARS (described in the zshparam manual and
referred to under forward-word but nowhere else in the zshzle manual).
Remove "/" to get the behaviour you want.

WORDCHARS=${WORDCHARS/\/}

If you'd like a more configurable way of doing this (having different
functions that either do or don't use / as a character in a word) see
the entry for the set of functions forward-word-match etc. in the
zshcontrib manual page.

(A while ago we were thinking about some contextual way of doing this so
that it would make /'s delimiters in file names, but nothing much came
of it.)

I don't quite remember where i got this from, but it does what you
want, http://mikachu.ath.cx/slask/dot-delete-to , if someone wants to
replicate it inline so it's archived go ahead, but i don't trust gmail
to get everything right.
