Keyboard shortcuts for date field

There are two keyboard shourtcut keys that you could use to enter today's date in Dynamics AX date field, namely the 'd' and 't' keys. The difference between these two keys is 't' is the machine date from Windows and 'd' is the session date which could be changed in Dynamics AX client Tools menu -> Session date. From the development perspective, 't' is the same as the today() method, and 'd' is same as the systemDateGet() method.
