Quick Key Problem Solved.
If you want the quick key to work for a particular favorite, the favorite MUST be included in the Scan list under the"Set Scan Selection", "Select Lists to Monitor".
The favorites here have to be set to "ON". You can then turn them on and off with the assigned quick keys.
If you have the favorite turned off in the "Set Scan Selection", the quick key will be inaccessible.
In other words, the "Scan Selection" list has precedence over the quick key.
