GoogleDesktopのショートカットキーを無効に

RadRailsとGoogleDesktopのショートカットキー(Ctrl+Alt+G)が競合してしまっていて、検索したいのにGoogleDesktopが出てきてしまう。鬱陶しいので何とか無効にしたい。色々捜したけど、中々見つからず、Googleのキャッシュに以下の文章が見つかった。

Tell me more about the CTRL+ALT+G shortcut key.

For a speedy way to search on Google Desktop, please try using our new Google Desktop shortcut key. To use this shortcut, simply press the Ctrl + Alt + G keys on your keyboard at the same time. This will bring your cursor to the search box on your Google Desktop Deskbar, Sidebar, or Floating Deskbar.

If you'd like to disable this shortcut, you can do so by editing the Windows system registry. Please note that editing the Windows registry is an advanced process, so you may prefer to contact your system administrator. If you decide to edit the registry, please follow these steps:

1. In "HKEY_CURRENT_USER\Software\Google\Google Desktop\Preferences,"
create a DWORD value named "hot_key_flags."
2. Set this value to "2" to disable only Ctrl-Alt-G, to 1 to disable onlyWindows-G, or to "0" to disable both Ctrl-Alt-G and Windows-G.
3. Restart your computer.

If, at any time, you'd like to re-enable both keys, simply set the value to "3" or remove the value entirely.

これから再起動します。
