Dictionary.contains(keyStr)
The expression:
$MyDictionary.contains(key)
is true if the dictionary contains the designated key.
Note that keyStr is literal string and not a regex pattern (unlike the operator's use chained with some other data types).
Dictionaries are case-sensitive, but Dictionary.icontains(key) is available for case-insensitive matching.
