(trick) working with hours, minutes, seconds

The angle key (Shift Multiply) has a similar dual purpose. It can be used to type polar coordinates directly, e.g. 1 angle (pi/4), and it can be used to toggle complex numbers between polar and rectangular notation once they're on the history stack.

The Base key (Shift Subtract) types a "#" when the most recent result isn't a binary integer, or it launches the Integer Editor if there is a binary integer there.

All of these keys, including the fraction button, operate by default on the most recent result, but they will also work on any other result if you select it first.

In CAS only, [a b/c] performs either approx(Ans) or exact(Ans) depending on what's on the history stack.

Did I miss any other non-obvious keyboard behaviors?
