Yes, keyboard shortcuts can vary across different operating systems and software. This is because the fundamental settings between operating systems differ, and each software has designed its own unique set of shortcuts based on its features.

Differences between operating systems:

• Windows: Uses the Ctrl key as the main trigger for shortcuts, e.g., Ctrl+C (copy), Ctrl+Z (undo).
• Mac: Uses the Command key as the core for shortcuts, e.g., Command+C (copy), Command+Q (quit app).
• Linux: Common shortcuts are similar to those in Windows, but specific desktop environments (e.g., GNOME, KDE) may add custom features.

Differences between software:

Even within the same operating system, shortcuts for the same actions can differ between software. For example:

• Text editing software: Shortcuts in Word, Notepad, and Google Docs are mostly similar.
• Design software: In Photoshop, Ctrl+T (free transform) is used, while in Excel, it's used for inserting a table.
• Browsers: Different browsers like Chrome and Firefox use similar shortcuts, but certain functions may differ.
