Removing messages from a pool dictionary
As you might suspect, removing pool dictionary definitions is also a lot like removing entries from a dictionary. A single entry can be removed using code such as the following: 
AddressApplication abtNlmRemoveKey: 'MsgNoName'
    poolName: 'AddressStrings' ifAbsent:[].
You can remove multiple entries using code such as: 
AddressApplication abtNlsRemoveAllKeys: #('MsgNoName' 'MsgSelect')
    poolName: 'AddressStrings' ifAbsent:].
abtNlmAddRemoveAll:poolName:IfAbsent: expects a collection of string keys for the first parameter. You may not substitute a dictionary.
