I'm surprised I haven't found an answer! But you see the pain in the ass kludginess of this. The only way to get to the other window(s) is to Mouse to it in the nav bar! There are Plenty of ways to switch between multiple tabs within one Chrome window, but NO Shortcut to switch between windows! Does anyone know a way around this? Is this a shortcoming of Google Chrome? I just spent 1/2 an hour trying to find an answer to this. Even if I multiple chrome windows open, CMD+Tab will only find one chrome one Chrome instance! Regardless of the application! If I have 25 separate chrome windows, It will tab through all 25 chrome windows! This is NOT the case in OSX (I JUST updated to 10.13.5 today). Windows will faithfully switch between ALL windows. On Microsoft Windows, if I do an 'Alt+Tab'. Consider this: I KNOW it's blasphemy to some to compare OSX to Windows, but I have both, and It is not unusual for me to have multiple Chrome browser Windows open at any one time. I don't know why I never picked up on this before, but WHY is it not possible switch between Chrome Windows in OSX with a keyboard short cut? Now, before you start firing off the glib 'command + ` ' or 'control + `' answer. On Mac, use Command + 1 through Command + 8 instead. Ctrl + 2 will switch to the second tab, and so on, all the way to Ctrl + 8. This shortcut is dependent on your operating system: On Windows, Chromebook, or Linux, use Ctrl+1 to switch to the first (leftmost) tab in your window.
