If you select the button you want to use for the alias macro and then select record macro (red button). Now you can use the window on the left to navigate (tree out the device) and select the page that has the button you want to alias to. Select that button and it will show up in the macro window along the bottom in the alias column. Repeat as needed for other buttons or devices and then select the stop macro button (black square). You can add delays, sounds, jumps or variables as you go or just insert them after you finish all the aliasing.

Hope this helps,
Ken
