Yeah this quick key thing is tough to grasp at first. The more you mess with it, it eventually sinks in.
Attached is a zip file for my Minneapolis area Favorites List. It should unzip to F81 - Minneapolis.HPE. You can then use Sentinel to import it. (It's what I use for when I travel to my home state of Minnesota.)
Envision a file cabinet. A Favorites List is that file cabinet. Each drawer in the file cabinet is a System. File folders in the drawer are Departments. Each piece of paper in that file folder is either a talkgroup or radio frequency.
Each particular "thing" has its own Quick Key. A Favorites List Quick Key (FLQK), is something that locks/unlocks the file cabient.
A System Quick Key (SQK) opens/closes the file drawer.
A Department Quick Key (DQK) opens/closes the file folders.
The keypress sequence for quick keys is FF.SS.DD (enter). FF is FLQK, SS is SQK and DD is DQK.
If you want to turn on/off the whole Favorites List it is FF (enter). A System is FF.SS (enter). A Department is FF.SS.DD (enter). In other words, how far down you go determines how many buttons are to be pressed.
Just to help me some, I stole an idea from another user. That is to incorporate Quick Key numbers as part of the FL, System and Department names.
Uniden has established sites as being at the Department Level. So what I do is assign Agency Departments with lower numbers and Sites as higher department numbers.
While what you have is fine, my version has ARMER as a system with the Agencies and Sites as being Departments. There are fewer numbers I have to commit to memory. I know anything "Minnesota" is "81.00.xx". From there, the "xx" depends on what I want to monitor, such as State Patrol, Fire, Interoperability, etc. (I usually leave all the sites on).
