I would like to remove the actions that I do not need, every time I rename an action it multiplies into something else like 0 meteactionjargon. I have a list of actions that I do not need, and I wont to remove them from the list
Go to the Outliner window and type animation in the search window. Choose the object that has the action you want to delete, hover the cursor over Animation block and press RMB-->Clear Animation Data. Save your file. When you close and reopen it the action'll be no longer there.
