Revit getting stuck inside commands, can't find the exit

 Sometimes Revit gets stuck inside commands, can't 'escape' out like AutoCAD.  Usually flipping to Modify or Home ribbon will reveal the cancel/OK buttons to get out.  I hit confusing situation recently with no cancel button to be found, as decribed by bulletproofdesign in this Augi thread:

When in a shape editing tool in the family editor (region, extrusion, etc), if you close the family, the 'load into family' button stays attached to your ribbon.... Clicking this suggests that there are 'no open projects' for you to load you project into....

Edit another family, click the 'load into family' button and it disappears...

Revit 2011 extensions are released, available to subscribers (that's everyone?)  After installation it's not clear where to find them.  The extensions don't automatically populate a menu, it has to be done manually.  Go to Add-Ins -> External Tools -> Extensions Manager.  Select a desired tool, right click and add to menu.
