First, open the QuickNote control panel (if it has been properly installed, you'll find it in the Control Panels folder in the System Folder).
You can set any key(s) to access the three different QuickNote note editing options from the QuickNote control panel (see “The QuickNote Window” below for more information on changing the settings).
NOTE: You should not use key combinations that are used by most applications such as Command-N, Command-O, Command-S, etc. (these are usually the commands for New, Open and save in most applications).
