What is the command in Awesome Window manager to let go of a key that has not been let go of?

My v key is locked up after I use the below snippet in my rc.lua file. ### Background Hotkey combinations are usually all pressed together at the same time. I am using the function key Fn which works as a key chain only because of the way it works with the firmware on my ThinkPad. Key chain means you press the Fn key, release it, then press another key. In other words, key chain keys are not pressed together but sequentially, one after the other. ### Setup My Fn key is XF86WakeUp. The following below is part of my rc.lua -- open edit ".vimrc" awful.key({ "XF86WakeUp" }, "v", function () awful.util.spawn("termite -e 'nvim /home/Dropbox/.vimrc'") end, {description = "Edit .vimrc", group = "Code"}), This snippet works just fine; I press Fn, release it, then press v and vim opens. Just as intended. ### Problem After I have used this keychain, Awesome will not let go of the v key and every time after that when I press the v key, for whatever reason, vim opens. This is less than ideal. How to stop this behavior in Awesome?
