In addition, the new property is used for both forward only and scrollable cursors for T2zos.
另外，对于T2zos，新的属性可用于单进游标和可滚动游标。
Television sets-with remote controllers capable of moving on-screen cursors only up, down and across, and then just one step at a time-are leagues behind the swiping gestures pioneered by the iPhone.
电视机——所配置的遥控器只能上下或横向移动屏幕光标，而且一次只能做一步操作——正与由iPhone倡导的触控手势结盟。
Because asynchronous transactions are used in Lite mode, you won't be delayed by wait cursors as you open documents and scroll through views.
因为在Lite模式中使用异步事务，因此在打开文档或滚动视图时，不会因等待光标而延迟。
