Note that on a US keyboard the ` (backtick) key is the one right below ESC.
If you have the keyboard in another locale (I use ES-intl) that hotkey doesn't make any sense at all: ` is next to "p" in my keyboard, and works only as a dead key. Cmd-` is literally impossible to use on it.
If you are in this situation, do yourself a favor and remap the "move focus to next window" hotkey [1]. It is very useful and I couldn't live without it now.
` (backtick) is also right above tab. On a US keyboard, this makes Cmd+Tab switch apps and Cmd+` switch windows of an app.
It's probably worth noting that the defaults remain on common Linux (at least KDE, GNOME, and Cinnamon) and Windows desktop shells with Alt instead of Cmd.
On Linux, Windows, and OSX, adding Shift cycles in reverse order.
