Talk:XUL:button

From MDC

For 1.9, the following is supported:

<button type="repeat"/>

This type of button, repeats its action while the button is being held down, much as scrollbar buttons or other arrow buttons do.

<button type="repeat" repeat="hover"/>

This button performs its command while the mouse is hovering over the button. The <autorepeatbutton> uses this type of button, but looks different.
