And here is the quick tip from Miladin who is a developer in Microsoft’s Internet Explorer 8 team,
Only those accelerators marked as “default” appear as the top level menu entries. This is meant for Accelerators that you use very often. All others can be accessed through the “More Accelerators” submenu so they really don’t take any space. So for Accelerators that you don’t use often but will still need from time to time – go to Manage Add-ons and rather than disabling simply select “Remove as Default”.
