Great!
While you're at it, Dorian recently added a new
left-button-drag function for
mousegestures, called 'SuperDrag', an updated version of the old 2011 plugin, but no hint anywhere in the GUI yet.
pref("kmeleon.plugins.gestures.SDLink", "openLinkInBackgroundTab");
pref("kmeleon.plugins.gestures.SDImage", "viewImage");
pref("kmeleon.plugins.gestures.SDText", "navSearch");
Someone explained me that means, you left-click on a link/image/selection, keep pressed and pull a bit right, and then the matching action is executed. So far it seems to work, not bad really (although personally I could live with doing the same on the 'right' button ;-))
