Xcode 4 (I use 4.3.3) has a nice feature - at the bottom of most navigator panels (left panel) there is a search field in which you can write a match expression to quickly find the object that you need. But I did not find a way to switch to this field from the code area without using the mouse / trackpad.
Does anyone know a shortcut that calls in Preferences-> Key Bindings?
Cmd + alt + j
Opens the project navigator and selects a search bar ready for printing. A.
Cmd + shift + J Just opens the project navigator.
I use...
Command + Shift + O
This opens a dialog box in which you can enter the name of the desired file, it also matches the expression.
