# Usage: py.exe mcb.pyw save <keyword> - Saves to clipboard
#        py.exe mcb.pyw <keyword> - Loads keyword to clipboard
#        py.exe mcb.pyw list - Loads all keywords to clipboard
#        py.exe mcb.pyw delete - Deletes all keywords
#        py.exe mcb.pyw delete <keyword> - Deletes a specific keyword
