The caret is a flashing line, block, or bitmap in the client area of a window or in a control that accepts keyboard input. It indicates the place at which text or graphics will be inserted. Because only one window at a time can have the keyboard focus, there is only one caret in the system.
上面是MSDN2000中对caret(脱字符)的解释，由此可以看出caret是指示输入焦点和插入位置的一个光标，比如你编辑文本是显示的光标。
