Provides a convenient wrapper for normalized keyboard navigation. KeyNav allows you to bind navigation keys to function calls that will get called when the keys are pressed, providing an easy way to implement custom navigation schemes for any UI component.
The following are all of the possible keys that can be implemented: enter, left, right, up, down, tab, esc, pageUp, pageDown, del, home, end. Usage:
var nav = new Ext.KeyNav("my-element", {
"left" : function(e){
this.moveLeft(e.ctrlKey);
},
"right" : function(e){
this.moveRight(e.ctrlKey);
},
"enter" : function(e){
this.save();
},
scope : this
});

Handle the keydown event instead of keypress (defaults to false). KeyNav automatically does this for IE since IE does not propagate special keys on keypress, but setting this to true will force other browsers to also handle keydown instead of keypress.
