Keyboard layouts for Windows and macOS differ significantly in terminology and key functions. For instance, the Windows Backspace key corresponds to Delete on Mac, while the Windows Delete key is known as Forward Delete on Apple devices. Similarly, the Enter key is labeled as Return on Mac, though a separate Enter key exists on numeric keypads.
Modifier keys also vary between platforms. Windows utilizes Ctrl, Alt, and Shift, whereas macOS employs Command, Option, Control, and Shift. Replacing keycaps is insufficient for cross-platform use, as the underlying scan codes must be remapped. Furthermore, Windows uses plus signs to denote keyboard shortcuts, while macOS typically lists them sequentially.
Functional keys and input methods show distinct behaviors. Windows uses F1 through F12 for system and application shortcuts, while Mac keyboards may extend up to F19. Additionally, macOS supports special character input via the Option key and a long-press menu for diacritics, features absent in Windows, which instead relies on Alt-code sequences for character entry.
Text navigation and application-specific shortcuts also diverge. macOS supports Unix-style control sequences for text editing and specific behaviors for arrow keys in text fields. Meanwhile, Windows retains legacy shortcuts like Shift+Insert for pasting and uses Home and End keys for navigation, contrasting with Mac's reliance on Command-based shortcuts.
