Windows like Alt-Tab (Cmd Tab) [duplicate]

I opened two Google Chrome windows (because I am using multiple Gmails) and when I do the Cmd ⌘ Tab ⇥ shortcut it just shows me other applications that I opened but does not show me the other Chrome windows that are already opened.

How to switch to the other Google Chrome window that I opened using keyboard shortcut?

UK Keyboard
[see below for other languages]

Cmd ⌘ `

Cmd ⌘ Shift ⇧ ` to go the other way.

Left of z on a UK keyboard [non-shifted ~ ]

Note: This only works if all windows are in the same Space, not if they are spread over multiple Spaces, which includes fullscreen. To overcome this, use Cmd ⌘Tab as usual and on the icon of the application you want to switch windows in press the down arrow key (with Cmd ⌘ still pressed). Then use left/right keys to navigate to the desired window across spaces and desktops.

You can also achieve this by clicking the app's icon in the Dock - this method will also switch to fullscreen windows, which the other methods will not..

From comments - You can check which key command it is for your language by switching to Finder, then look at the Window menu for 'Cycle through windows'...

BTW, specifically in Chrome, Safari & Firefox, but no other app I know of on Mac, Cmd ⌘ (number) will select individual tabs on the frontmost window.

It also would appear that Cmd ⌘ ` is yet another of those language-specific shortcuts; so if anyone finds any more variants, please specify for which language & keyboard type.

Unfortunately, as of July 2021, Apple has changed this page, making it useless for our purposes:/
If anybody finds new combos for different languages, please check Keyboard layout here - Apple KB: How to identify keyboard localizations - & add that as well as which Input Source you use in System Prefs > Keyboard > Input Sources.
Add a keyboard picture from the KB page too, if that would help.
That will make it easier for future Googlers.

Further info:
You can change the keys in System Prefs > Keyboard > Shortcuts > Keyboard...
though it doesn't list the reverse direction, it does still work when you add shift to that new combo. I tested by moving mine from ` (and ~ ) to § (and ± )

You can use the alternative of Ctrl ⌃ F4 [visible in the prefs window above] but that almost indiscriminately marches through every single open window on all Spaces, without switching to the correct Space each time. It's really not too useful unless you use a single Space, just included here for completeness.

On US keyboard:

Next window: Command ⌘ `

Previous window: Command ⌘ Shift `

` is the key on top of Tab key, so it's similar to Command ⌘ Tab shortcut.

On other language:

Go to System Preferences -> Keyboard -> Shortcuts -> on the left menu, select Keyboard -> on the right menu, select Move focus to next window. You can now change the shortcut to which ever key is on top of Tab in your keyboard to work like intended.

Attention:
Doesn't work when window is in full-screen. In that case, you have to use Mission Control shortcuts, e.g. Ctrl ⌃ → and Ctrl ⌃ ←

Cmd+` of course will work but I do it in different way.

I do the Cmd+tab when i do that, I dont release the Cmd so the opened apps are still visible. While it is visible, I will press ▼.

This way it will show all your opened application with animated displayed so you can navigate using arrow keys.

Swiss & German keyboard:

Cmd ⌘ <
Cmd ⌘ >

I figured out why cmd` doesn't work half the time. Your applications can not be in full screen mode, which is kinda silly but I tried it on the Finder window like mentioned above, no problem. Took both chrome windows out of full screen and the shortcut works like a charm.

UPDATE

The best I could come up with is pressing ctrlleft or right on your keypad. It cycles through all your full screen windows, but hey at least it's something.

Also North American keyboard settings, though I don't think that actually matters since the issue, assuming at least, is the app was fullscreen.
