Sublime text 3 change focus to next split view pane

How can I easily switch the active pane to the next pane in my SplitView ?

Suppose I am working with a vertical split view of 2 screens, and I need to rapidly change the focus from view n°1 to view n°2 to copy paste various elements

Currently I found no other means than to click the other pane to change the focus. Is it possible to have a keyboard shortcut that would cycle through split views ? (Sometimes I have 3 vertical splits and would like to have something similar to the Alt-Tab shortcut but for the split views only.

Is it possible to have a keyboard shortcut that would cycle through split views?

I don't think you can cycle, but you can go direct to a view:

Ctrl+1..4 - Jump to group where num is 1..4
