Concreteexamples include "press", "release", "click" for buttons, "drag"(meaning initiate drag) and "drop" for drag sources and drop targets,etc. </p><p>Though most UI interactions on components should be invocable viakeyboard as well as mouse, there will generally be a close mappingbetween "mouse actions" that are possible on a component and theAtkActions. Where mouse and keyboard actions are redundant in effect,<a href="AtkAction.html" title="AtkAction">AtkAction</a> should expose only one action rather than exposing redundantactions if possible.
