Place: Search field in "Elements" A HTML class/id attribute value with a dash (maybe other none alphabetic chars, too) is not found. Example: There is a element <form action="/" method="post" class="search-form"> ... Searching for "search-form" will not return any results. Even a search for "search" will not find the desired element. A class value like "searchform" would be found.

This was partially fixed in r37288 by using getElementsByClassName. But the partial match should still work. This might be an XPath bug.
Well, but you still cannot find all classes/ids in the Web Inspector.
Fixed with recent pfeldman's major search cleanup.
