Customizing shortcuts

Open settings (⌘/Ctrl + ,)
Click the Key Shortcuts tab (keyboard icon)
Click any keybinding to enter recording mode
Press the new key combination you want to use
Press Escape to cancel recording without saving

If the key combination you record is already used by another command, Nuclear will show an error and keep the previous binding.

To restore a single shortcut to its default, click the Reset button next to it. To restore all shortcuts at once, click Reset all to defaults at the bottom of the page.

Custom shortcuts are saved to shortcuts.json in your Nuclear config directory and persist across restarts.
