4. Right click the result then select Add Keyboard Shortcut
5. Type any keyboard combination you want, for example, me prefer shortcut Ctrl + K to reveal current editing file on project explorer
6. Click OK button. It will prompt you to remove keyboard shortcut you typed from existing command, so just click Remove button.
