通道滑鼠事件也有类似的问题。
例如，您可以在不影响功能表事件处理常式或键盘事件处理常式的情况下，取代滑鼠事件处理常式。
For example, you can replace mouse event handlers without affecting menu event handlers or keyboard event handlers.
此外，如果使用者并未使用电脑(没有发生任何键盘或滑鼠事件)，则系统不会将此时间计算为逾时。
In addition, if the user does not appear to be using the computer (no keyboard or mouse events are occurring) then the system does not count this time towards the timeout.
如果您从取得焦点或捕捉的项目接收到这个事件，实际上此时滑鼠指标可能是在另一个项目上方。
If you receive this event from a focused or captured element, the mouse pointer might in fact be over another element at the time.
通常，只有在已知有要解决的处理问题，例如来自滑鼠或键盘事件的输入系统处理问题时，您才应该这样做。
Generally, you should do this only if there is a known handling issue you are trying to work around, such as input system handling from mouse or keyboard events.
有些组合键可能无法运作、有些滑鼠活动可能无法运作，或者可能会引发一些预期的事件。
Some keystroke combinations may not work, some mouse activity may not work, or some events may not be raised as expected.
另外，此事件也会提供有关进入编辑模式所使用之键盘和滑鼠笔势的资讯，并可让您选择取消编辑模式。
Additionally, this event provides information about the keyboard or mouse gesture that was used to enter editing mode, and gives you the option of canceling edit mode.
滑鼠左键按下事件是最有可能在控制项中包含类别处理的事件。
The left mouse button down event is the most likely event to have class handling in a control.
