In Sublime - how to switch between panels in a 2-column view?

Does anyone know how to - using the Sublime 3 text editor - use keyboard commands to toggle back and forth between columns in a 2-column view? I haven't been able to find any documentation or Stack Exchange posts that describes how to do this.

thanks

How do I split view in sublime?

To view two row (horizontal) panes side-by-side use the shortcut SHIFT-ALT-UP-2 (PC) or SHIFT-OPTION-⌘-2 (Mac). Replace the last stroke with “3” to view three panes respectively. If you want to split a pane further, you can use ST3's “Group” feature.

Ctrl+column number will set the active column to the column number you choose, so with 2 columns you'd use Ctrl+1 and Ctrl+2.
