Today's date on the press of one key

Is there currently a way to enter today’s date with the stroke of one key?
e.g. working with keyboard mainly and need to update a date.
There’s a few clicks or keystrokes required to update an existing value to today’s date.
It would be great if date could be resolved to today’s date (or even with current time if date/time field) when only one letter, e.g. ‘t’ is entered and then tabbed out of the field.
It would enhance usabilty. A neat little feature that I came across in some other application before. Loved that little feature and it would be a great enhancement.
