allow-tab-exit

Gets or sets whether tab-exit is enabled for the editor canvas. When tab-exit is enabled, the user can move the keyboard focus out of the editor using the Tab and arrow keys, or invoke the default button using the Enter/Return key. By default, tab-exit is disabled.

When tab-exit is enabled for an editor canvas, Tab, arrow, and Enter keyboard events are consumed by a frame's default on-traverse-char method. (In addition, a dialog's default method consumes Escape key events.) Otherwise, on-traverse-char allows the keyboard events to be propagated to the canvas.
