Miscellany

If you want to change the background color of a word, you would need to type two numbers separated by a comma instead of just one number. The first number is the text color, the second number is the background color. The colors range from 0 to 15, and the indexes are:
       0 white                8 yellow
       1 black                9 lightgreen
       2 blue                 10 cyan
       3 green                11 lightcyan
       4 lightred  	      12 lightblue
       5 brown                13 pink
       6 purple               14 grey
       7 orange     	      15 lightgrey
