This explains the functional steps within the sequence. For all the other XML details please refer to Formats and syntax

Most likely selecting by user number is the more common way as you can easily implement your own system of user numbers. However this example shows the use of Location refering to the current as well as a particular other page.

Edit the macros to suit your needs regarding userNumber and location.

1. make this macro available
2. fire the macros to select a specific timeline
