In Google search Window enter
Set Timer 30 seconds
and press Return
Immediately a timer in its own small window, (in the space where you
expect results) starts. When it counts to zero alarm beeps till you
switch it off. This appears to be an undocumented command. I used an
application called kitchen timer (egg timer) earlier.
Now when I am on PC, if I have to switch off Pressure Cooker or Water
motor / pump, I set this timer in a separate window!
