accesskey

accesskey 全局属性提供了为当前元素生成键盘快捷键的提示。属性值必须由单个可打印字符组成（其中包括重音字符和可由键盘生成的其他字符）。

¥The accesskey global attribute provides a hint for generating a keyboard shortcut for the current element. The attribute value must consist of a single printable character (which includes accented and other characters that can be generated by the keyboard).

注意：在 WHATWG 规范中，它表示你可以指定多个空格分隔的字符，浏览器将使用它支持的第一个字符。但是，这在大多数浏览器中不起作用。IE/Edge 使用它支持的第一个命令没有问题，只要不与其他命令冲突。

¥Note: In the WHATWG spec, it says you can specify multiple space-separated characters, and the browser will use the first one it supports. However, this does not work in most browsers. IE/Edge uses the first one it supports without problems, provided there are no conflicts with other commands.
