API Frame SetPropagateKeyboardInput

Sets whether keyboard input is consumed by this frame or propagates to further frames. Frame:SetPropagateKeyboardInput(propagate)

• propagate: - true to propagate keyboard input further, false to consume keyboard input immediately.

• Keyboard events are dispatched to the / script handlers of frames based on their layering order, stopping upon encountering the first frame which consumes input rather than propagates it.
• Keyboard bindings are handled by the WorldFrame, so if any non-propagating keyboard-enabled frame is visible, no keyboard bindings can be triggered.
• You can call this function from script handlers to consume only some keyboard events. If your frame propagates handling of the OnKeyDown event, it will not receive the OnKeyUp event.
