No. The listed contexts include Ubuntu Linux 24.04 LTS, Microsoft Excel, Photoshop, Microsoft Teams, Spotify, Google Sheets, Microsoft Outlook, Adobe Illustrator, Adobe Acrobat. Check the table for each application and platform: the active window, keyboard layout and application settings determine which command receives the key press. An application being available on an operating system is not evidence that this exact binding works there.
