Remap broken "Tab" key to a function key on MacOs Sierra I need to remap the tab key to a function key, as the Tab is broken. I've looked at Karabiner, but it doesn't work on Sierra
While Karabiner does not work in MacOS Sierra they offer Karabiner Elements which has a subset of Karabiner's features.

One of the features it does have is the ability to map a function key to tab.
