tool tip

基本解释

If you hover your mouse cursor over a diagram element, a tool tip from the documentation for that element will pop up.
如果您将鼠标停在一个图表元素上，那么就会出现一个工具提示告诉您关于此元素的信息。
If the selection is a file (rather than a folder), then we adjust the text and tool tip to reflect that file name and enable it.
如果选择是文件（而不是文件夹），则调整文本和工具提示以反映该文件的名称并启用它。
For example, if you decide to display help information as a tool tip rather than in a separate window that would open by user request, the tool tip might not be accessible to screen reader users.
例如，如果您决定将帮助信息作为工具提示，而不是在由用户请求打开的单独的窗口中，工具提示可能对屏幕阅读器用户是不具有易访问性的。
