Time measurement of a function

In CAS (only), there's a cool shortcut for timing any expression; just press
Sto, comma, Enter
after the expression that you wish to time. It looks like "►," until you press Enter. (Sto can be typed either from the Sto menu button or Shift EEX).

Example: wait(2)►, Enter
Magically turns into: time(WAIT(2))
Returns: 2 (approximately!).

Notes: The time() function is similar to the TEVAL() function, but returns the seconds without any unit appended. Although the 3-keystroke shortcut only works in CAS, the time() function works in both Home and CAS... but "time" must be spelled in lowercase.
