In Sentinel you can click on Edit Favorite, select and click the Favorite List and from there, Sentinel will show you the Favorite List Editor window, where you can see at a glance, whatever Quick Key number you've assigned to a particular System.
From there, select a department, and Sentinel will show you Quick Keys assignment for each department.
Click on a Department (in the left hand column) and now you will see three tabs; Channels, Options, Location.
Clicking on Options will now show you the Quick Key assigned to that channel.
So...there'e no quick and easy way to see everything at a glance in Sentinel, which is what I am most familiar with.
Maybe ARC or ProScan does, but I don't use any of those to program my SDS200.
