However, it is not that easy, since sometimes the tabs can appear in the UI automation collection out of order. For tabs appearing further in the collection Ctrl+ Tab is pressed repeatedly until the desired tab is reached. The trick is to press Ctrl+ tab index to activate the tab in the case its position is between 1 and 8 (9 switches to the last tab, see Chromebook keyboard shortcuts). Thanks to this GitHub project I was able to activate the correct Chrome tab. Since Chrome doesn't fully implement Windows Automation features, it has to be implemented differently. The only thing you need to remember is that searching of tabs for minimized Chrome window is impossible.
