Step 2 :
Creating the Colored Square MC for the Key
The next movieclip you need is keysymbol, a square graphic (or whatever shape you want) turned into a movieclip by choosing the Insert> Convert to Symbol command. This clip is placed off stage (the blue square at upper right in the .fla file) since it will not be used itself (only duplicates of it). Use the Instance Panel to give this an instance name of "mcKey".
