Remove Menu bar in Opera 10

I was looking for the way to remove Opera's menu bar since I have my Acer ONE. And today I found the way to make it disappear thanks to this post http://www.aswinanand.com/2008/12/hide-menu-bar-in-opera/ I took the information form the post. (http://www.aswinanand.com/) 
 
1. Go to Tools -> Preferences.
2. Click the “Advanced” tab.
3. Select “Shortcuts” from the left side menu.
4. Select “Opera Standard” under “Keyboard Setup” and click on “Edit” button.
5. From the “Edit Keyboard Window” popup, select “Application” and then on “New” button.
6. Now type “F10″ without quotes, press Tab key & then type “Enable menu bar | Disable menu bar” without quotes.
7. Now click “OK” button on both the windows. 

That's all!
