Bug 31249 Bad default modifier for Hyperlink style navigation on MacOS X
M5 The default modifier for hyperlink style navigation is "Control" which doesn't work well on MacOS X because here the Control modifier is used to simulate a right-click (opening the context menu). The consequence of this is that if control is pressed the users gets the underlined text style when hovering, but he cannot follow the link because a click results in opening the context menu. The default on MacOS should be 'Command'
