Rob Wilkerson reminded me in yesterday's post regarding XRAY to mention the MRI bookmarklet from Westciv as well. From WestCiv's site: "MRI is a free cross browser tool that lets you test selectors with any web page. Selectors, particularly complex ones can be difficult to get exactly right - MRI lets you experiment with them on any web page (local or online, static or dynamic).
Essentially, MRI lets you search and identify specific selectors on your web page. Selectors are the names or tags that you specify in your CSS so that you can "select" which elements to style. So MRI will help you find all anchor tags within a list item (li > a), or all elements with a certain class or ID.
I put this as a "nice to have" since I don't think it's as useful as XRAY is. It's more often that I'm wondering "why on earth is this particular element styled/not styled this way?", which XRAY will tell me, than I wonder "which elements have this certain selector?"

Completely agree. I don't use it often, but do find it handy from time to time. It's just an inexpensive (cost- and resource-wise) addition to the toolbox which is why I mentioned it. :-)
