I've created three different screen splits with custom key commands with DFP but I don't know how to access them. When I press the three keys, nothing happens other than a pop up saying "Monitor Profile Loaded".

With Functions, I was able to create different configurations that were easy to access with Title Bar icons. Can I access my different custom splits via Title Bar icons? How do I use the custom key commands?

For example, if I have a number of tabs/window open and I want to put them into a custom 3 split, how do I get each window into the disired split? I know how to do it with Functions but those are predetermined.
