This is Radioactv Biohazard, and i'm going to show you how to use 'ALT - Keys'.
Have you ever seen people using these cool symbols like a upside down ? and won't tell you how? I'm not like those bad eggs. I'm going to show you how!
Step 1: How to do it
To do this on a normal computer, hold down ALT
To do this on a Lap Top, hold down FN
Make sure the NUM-Lock is ON
So, all you have to do is hold down ALT or FN and type in a number code. Then let go of Alt or Fn and it will appear! A list of various symbols are on the next page!
