This method is called if no other view in the current view hierarchy is bound to the escape or command-. key equivalent. You can use this to cancel whatever operation is running.

Called when a touch begins. Capturing a touch is a special case behavior that allows for the nesting of touch capable views. In some situations, an outer view may want to capture a touch before* the inner view acts on it. For example, a container view may want to act on swipes or pinches, while the inner view may only respond to taps. If the normal event path was followed, the inner view would get the touchStart event and by accepting it, would inadvertently prevent the outer view from being able to act on it.

For this reason, when a touch begins, each view from the top-down has a chance to capture a touch first, before it is passed to the bottom-most target view. For example, SC.ScrollView captures touches so that it can determine if the touch is the beginning of a swipe or pinch. If the touch does become one of these gestures, SC.ScrollView can act on it. However, if the touch doesn't become one of these gestures, SC.ScrollView understands that it needs to pass the touch to its children.

Therefore, implementors of captureTouch are expected to release the touch if they won't use it by calling the touch's captureTouch method and passing themself as the new starting point (capturing will continue from the implementor onward as it would have if the implementor hadn't temporarily captured it).

Note, captureTouch is only meaningful for container type views where their children may handle touches as well. For most controls that want to handle touch, there is no reason to capture a touch, because they don't have any children. For these views, simply use the touchStart, touchesDragged, touchCancelled and touchEnd methods.

Called when a contextmenu event is triggered. Used to disable contextmenu per view.

Delete the current selection or delete one element backward from the current selection.

Delete the current selection or delete one element forward from the current selection.

A field editor might respond by selecting the field before it.

Insert a newline character or end editing of the receiver.

Insert a tab or move forward to the next field.

Insert the text or act on the key.

Called when the mouse is pressed. You must return YES to receive mouseDragged and mouseUp in the future.

Called when the mouse is dragged, after responding YES to a previous mouseDown: call.

Called when the mouse enters the view and the root responder is not in a drag session.

Called when the mouse exits the view and the root responder is not in a drag session.

Called when the mouse moves within the view and the root responder is not in a drag session.

Called when the mouse is released.

Move the insertion point/selection down one (i.e. down arrow key)

Move down, extending selection - shift || alt

Move insertion point/selection backward one. (i.e. left arrow key)

Move left, extending the selection. - shift || alt

Move the insertion point/selection forward one (i.e. right arrow key) in left-to-right text, this could be the left arrow key.

Move right, extending the seleciton - shift || alt

Move insertion point/selection to beginning of document.

Move insertion point/selection to end of document.

Move the insertion point/selection up one (i.e. up arrow key)

Move up, extending the selection - shift || alt

Page down

Page up

When the user presses a key-combination event, this will be called so you can run the command.

Select all

Called when a selectstart event in IE is triggered. ONLY IE We use it to disable IE accelerators and text selection

Called when a touch previously claimed by returning `true` from `touchStart` is cancelled.

Called when a touch previously claimed by returning `true` from `touchStart` ends.

Called when an active touch moves. The touches array contains all of the touches that this view has claimed by returning true from touchStart.

Called when a touch begins. You must return YES to receive touchesDragged and touchEnd in the future.
