Frequently Asked Questions

**Q: How do I create custom keyboard shortcuts?**

A: Use your operating system's keyboard settings (Windows: Settings > Ease of Access > Keyboard, macOS: System Preferences > Keyboard > Shortcuts, Linux: Settings > Keyboard > Shortcuts) or third-party tools like AutoHotkey, Keyboard Maestro, or xdotool.

**Q: Why don't some shortcuts work in certain applications?**

A: Applications can override system shortcuts with their own key bindings. Check the application's menu or preferences for shortcut customization options, or use application-specific shortcut references.

**Q: How can I type special characters without memorizing Alt codes?**

A: Use your system's character map (Windows: Character Map, macOS: Character Viewer, Linux: Character Map), enable compose key functionality, or use text expansion tools for frequently used symbols.

**Q: What's the difference between Ctrl and Cmd key functions?**

A: Ctrl is the primary modifier on Windows and Linux systems, while Cmd (⌘) serves the same function on macOS. Most shortcuts translate directly (Ctrl+C on Windows = Cmd+C on Mac), but some system-specific shortcuts differ.

**Q: How do I fix sticky or non-responsive modifier keys?**

A: Check accessibility settings for sticky keys, clean your keyboard, test with an external keyboard, update drivers, or reset keyboard preferences. Physical issues may require keyboard replacement or professional cleaning.
