This browser-specific property is not recommended. Authors should generally find an alternative way to accomplish the same task while adhering to all best practices, or simply do without it if it is unimportant.
The accelerator property is used in CSS and certain HTML elements. This property is a Microsoft CSS Extension, and since Windows 2000, it has the ability to turn off its system underlines for accelerator keys until the ALT key is pressed (then the accelerator underline hint is displayed). This property should have no effect in previous Microsoft OS versions, and if this system capability is turned off (or "on", depending on how you look at it), it will also have no effect. While this works for underlined elements (<u>), it also seems to work for any element, although a different pseudo-underline color seems to be generated in such cases.
Values[]
true- The element contains an accelerator key sequence.false- The element does not contain an accelerator key sequence.
HTML example:
<u style="accelerator:true;">TEXT</u>TEXT
