Complete Xcode Keyboard Shortcut List (UPDATED)
I have finally jumped into the bandwagon of Objective-C development with XCode, out of curiousity to develop an iPhone application. And the first thing that I usually did when playing with a new IDE or editor is to learn the shorcuts. Alt+Shift+Up -> Switch between header and implementation files Alt+Shift+Left -> Switch to the previous opened file Alt+Shift+Right -> Switch to the next opened file Cmd+Double Click -> Jump to the file definition for the clicked class name Alt+Double Click -> Jump to documentation window for the clicked word Shift+Cmd+D -> Open file quickly Shift+Cmd+C -> Open Class Browser window Ctrl+? -> Open documentation window Ctrl+Alt+? -> Open research assitant window Ctrl+1 -> Show opened file dropdown Ctrl+2 -> Show methods drop down Option+Escape -> Edit completion list Ctrl+Period -> Move to next completion list Ctrl+/ -> Select next placeholder in auto completion brackets Cmd+/ -> Comment text

iphone - How do I use the ios 4.2 base sdk using Xcode 4.2? - Stack Overflow
Xcode 4.2 comes with device support for iOS 4.2+ already installed. You don't want to change the base SDK, you need to change the deployment target. By default, the deployment target for a new project in Xcode 4.2 is set to iOS 5.0. You can change that either on the project settings summary screen or in the project settings configuration settings (it's fairly obvious on the summary screen, and just search for 'deployment target' on the full settings screen).Xcode presents you with a dialog when the simulator needs to be downloaded. Documentation preferences has consequently been replaced with Downloads preferences, including both documentation and components (simulators and SDKs). Using the Components tab of the Downloads preferences pane, you can view a description of each available component, download and install it. by Mar 1
