I forget stuff--
control + C : To kill whatever is running
up arrow key : For last command
control + A : To get to the beginning of the line
control + E : To jump to the end of the line
control + L : To clear terminal/screen
control + H : Similar to Backspace
control + K : Clears after cursor
control + W : Clears before cursor
-- so I'll be adding to this.
NOTE: I'm on a Mac
