On Debian 13 with GNOME, you can switch between windows of the same application within the current workspace using the following methods:
1. Default Keyboard Shortcuts
Alt + ` (backtick)
Switch between windows of the current application.
Super + ` (backtick)
Same as above, but with the Super (Windows) key.
**Super + Number (e.g., Super + 1)
Switch to the first window of the application pinned to the dock.
**Alt + Tab
Switch between all open windows (not limited to the same app).
2. Alternative Methods
- Click the Application Icon in the Dock: Hovering over an application's icon in the dock (left sidebar) will show all open windows of that app, which you can click to switch.
- Use the Overview: Press
Super (Windows key) to open the Activities overview, then start typing the application name and select the window you want.
3. Customization
If these shortcuts don’t work for you, you can customize them in:
Settings → Keyboard Shortcuts → Navigation or Windows.
