Details on Timing Belt Replacement

Just one more question,
What do people mean when they say "Make sure the belt don't jump a tooth"?

IN OTHER WORDS--WHEN THE BELT IS INSTALLED CORRECTLY, ALIGNMENT MARKS ARE LINED UP IN CERTAIN MANNER. IF THEY WERE NOT LINED UP CORRECTLY THE VALVES ARE NOT GONNA OPEN AND CLOSE AT THE RIGHT TIMES.

WORST THING IS, IF THIS IS A "INTERFERENCE ENGINE" IF THE VALVES ARE NOT "IN SYNC" WITH THE PISTONS GOING UP AND DOWN, THEY HIT EACH OTHER AND MAJOR DAMAGE OCCURS.

THIS MIGHT HAPPEN BECAUSE THE BELT IS_____INSTALLED WRONG_______BROKE (POSSIBLE BECAUSE IT WAS NOT CHANGED AT RECOMMENDED MILEAGE_______THE BELT (STRETCHED OLD BELT OR ENGINE WEAR) SORTA CLIMBS OVER THE COGS, ONE OR MORE.

THIS LAST SITUATION (ABOVE) PUTS IT OUT OF TIME TOO. THIS IS CALLED JUMPING A TOOTH, OR JUMPING TIMING.

THIS SAME SITUATION CAN HAPPEN WITH VEHICLES WITH A "TIMING CHAIN" IF THE CHAIN IS REAL WORN OR STRETCHED, IT WILL START CLIMBING THE COGS.

EVER HAD A REALLY RUSTY BICYCLE CHAIN, ON A BIKE? AS YOU PEDAL, THE CHAIN'S LINKS DON'T FLEX/ BEND AT THE PIVOT POINTS....USUALLY THE CHAIN STARTS SORTA JUMPING OVER THE TEETH/ GEAR/ COGS.......THAT IS THE MEANING OF "JUMPING A TOOTH/ TEETH"

DECENT EXPLANATION?

Here's one thing to watch out for when removing the old belt and installing the new one:

Before removing the old belt, mark it where the marks on the camshaft and crankshaft sprockets are before releasing the tensioner, then remove old belt, copy marks from old belt to new belt (there may be marks on the new belt, just make sure they line up with yours), install new belt with marks lined up with corresponding marks on sprockets (sprocket marks may not be lined up with marks on engine yet). Then when you release the tensioner the marks on the sprockets should line up with the marks on the engine.
