Shortcuts · Apps and windows
Cycle windows within one app: the Mac and Windows shortcut
macOS
Command+`
Windows
No single key — Ctrl+click the taskbar icon
What catches people out
Windows has no ⌘` equivalent: Alt+Tab walks every window on the machine, not that app's. Ctrl+click an app's taskbar icon steps through its windows, and Win+1…9 pressed repeatedly does the same for a pinned app.
