Multiple Match Type

This little feature has escaped me for who knows how long, and I confess to finding it in 2009, and not 2010 (though I grabbed my screen shots from there). 2010's Ribbon also makes it far more obvious then in the old UI. But here it is. When you use Match Type (MA on the keyboard) in the options bar is a little check box option appears "Multiple". Check it, and you're dropped into a selection mode where it is very easy to select multiple objects whose Type you want to change to your "base" type. Click on the "Finish Selection" button and all the types change at once!
