Found this useful query at http://id.motd.org/pivot/entry.php?id=22. The b.parent=2 in the command refers to the bookmarks folder to extract. See the source webpage for additional info.
If you add the bookmarklet to your browser's bookmarks with like say, the keyword 'cfu', you can for example type 'cfu hello' in the location bar and the %s gets replaced with 'hello'.
The bookmarklet will convert the search text to base64 for use with the commandlinefu website and will take you there. Tested with Firefox.
pushd and popd are your friends, but sometimes they're just incompatible with the way one works...
Two shell functions:
bm bookmarkname - "bookmarks" the current directory, just 'cd $BMbookmarkname' to return to it.
forget bookmarkname - unsets the 'bookmarkname' variable. It isn't mandatory, they cease to exist when the session ends.
