What is the way to quick-switch between tabs in Xcode 4

The default shortcuts are:

• ⌘ + SHIFT + { - Select Next Tab
• ⌘ + SHIFT + } - Select Previous Tab

But I prefer going to XCode -> Preferences -> Key bindings and changing them to:

• CTRL + TAB - Select Next Tab
• CTRL + SHIFT + TAB - Select Previous Tab

...so they work the same as in Chrome or Safari.

Shortcuts are:

• CMD + SHIFT + } - Select Next tab
• CMD + SHIFT + { - Select Previous tab
