Smart Keylogger

Smart Keylogger logs the keystrokes you type. Includes option to log only when certain strings are found in the active window's caption. Completely commented. Note: Due to me getting bored with this project :x and my desire NOT to find out tons of chr numbers, It only logs numbers, letters, tab, spacebar, and enter. I'd appreciate any feedback, and please take the time to vote if you find this useful :]
