Turn your watch into a compass: "Hold your watch horizontally and point it so that the hour hand is facing into the sun. At the center point between the 12 and the hour hand is your north/south line, with north facing away from the sun. So if the hour hand is pointing at 4, for example, the 2 would point towards the south, and the 8 would point towards the north. Just remember, this only works in the Northern Hemisphere; and during Daylight Savings Time you would use the 1 instead of the 12 to determine the center line." -Amarnath Ganesh

An example is "/pi" (no quotes), that would auto-correct to the actual Greek character." -Trey Brisbane
