It's logical, and the SELECT will test each CASE until it finds a 
matching, whereas the first method using a collection is an hash 
followed by a direct access.

Otherwise, I plan to add a Key property that returns the pressed key as 
a string with key and shortcut (For example "CTRL+A"). This string can 
then be tested directly or used as a key inside a collection.

It will make the code more readable than testing Key modifiers property 
and Key codes.
