If your flash movie is fairly complex, or needs to be keyboard accesible, you may want to implement some keyboard shortcuts to simplify things for your user. Using a combination of the "Ctrl" key (or Cmd, if you're mac-inclined) and a letter key might seem like a natural choice. However, there are a couple reasons why this is bad:

1. Flash doesn't take keyboard priority in all browsers.
In Windows (XP), Chrome, Opera, and FireFox allow Flash Player to intercept the keyboard input, so if you make a "Ctrl+t" shorcut in your movie, pressing that key combination won't open a new tab anymore (as long as the flash movie has focus) - it'll do whatever your flash movie says "Ctrl+t" should do.
