Action Management Search feature by Action number

Action Management Search feature by Action number

Hi -  if anyone has learned how to search for an existing Action by the Action number, not by Record (I don't always know what Record it might be under) please let me know?  I couldn't find the feature in AE, it is in JD now and we use it daily.  We'll get an email directing that we all do something with the requirement to note that we completed in, in the Action.  The email has the Action number tag on it in JD.  Online / Help  etc-  looked and was unable to find the Actions Management Search function by Action number in AE.  Thanks!
