Inherits From:

Declared In:

EDKeyControlWindow.h

Class Description

The exact behaviour is determined by a "key binding" dictionary which is loaded from a file named KeyBindings.dict in the application's main bundle. This can be overriden by a file in any of the applications library directories.

The dictionary uses the keyboard key as key and the selector as value. A tilde character preceeding the key name is interpreted as ALT modifier and a caret as CTRL modifier. Alternatively, the value can be another dictionary in which case this sub dictionary becomes active after the corresponding key was pressed. When a key not defined in the sub dictionary is pressed, the main dictionary becomes active again. If a sub directory contains the key "prompt" the corresponding value is displayed in the prompt field when the sub directory becomes active.

Example: Consider the following file:     
    
    {    
        n = "gotoNext:";
        "^x" = {    
            prompt = "x-tras";
            s = "save:";
        }
    }
    

If the user presses n the selector gotoNext: is sent. If the user presses CTRL-x the prompt field appears and shows the text "x-tras". Pressing s now results in the selector save: being sent.
