So I've already referred a question that demonstrates how to bind the Synapse launcher to the "Super (Win) Key". (Can I change Synapse shortcut to Super/Windows key alone?)
The problem is that combinations involving the Super key now all launch Synapse.
I believe this is happening because Synapse is being activated on the button-press event rather than on the button-release event as would happen with, say, Unity or while using it on Windows.
Is there any way in Ubuntu to bind a shortcut to the button-release event? That way I can use the Super button in other combinations, like "Super + D" for show desktop or something.
I'm using the Gnome (Compiz) Flashback session environment on Ubuntu 14.04 LTS.
