Usage notes
- Key names are case-sensitive and must match the actual information dictionary key exactly, otherwise nothing happens
- If the specified key does not exist in the information dictionary, this method will silently return without raising an exception
- Deletion operations only affect the document structure in memory; the save method must be called for changes to be written to the file
