Sheesh! There are so many of them!
Not many of us would be able to memorize them all.
So, you'd need to print a cheat sheet.
I bet some of 'em would take awhile to find on the list.
So, it would be quicker to do it the "long" way!
I guess the point is to memorize the ones you use often, and learn the ones that take the longest to execute otherwise.
