title: Flash CS6 Edit multiple keyframes
body: <p>I have symbols on a stage that are in all keyframes.  I want to modify the properties of 2 symbols on all of the keyframes.  Multiple Edit does not work, or I don't know how to make it save the changes. if there is a trick to make this happen, I can't seem to find it.  I select Edit Multiple frames.  Then I select the frames with the slider ends on top of the timeline.  I make the changes and click on the Edit Multiple frames button.  I have 500+ frames and changing all of these properties are driving me nuts....</p>
