Input Option upon release of Cmd+Tab

Question

When using the application switcher triggered by Cmd+Tab, selecting an application does not necessarily bring forward the window of that application. One can however use the Option key. Then, when releasing Cmd+Tab, the window will be brought forward.

I'm using this complex modification (from the repository) in Karabiner to remap Cmd+Tab to Cmd+'. How can I modify this so that Option is inputted upon release of Cmd? Simply adding it as a modifier doesn't work.

I am not sure how you can do that with vanilla Karabiner.

If you are OK with using Goku, the following snippet I just tested does what you'd expect. In my case, on pressing Fn and holding it, it's just a regular Fn press. If you press and release it does a Cmd+Tab and holds LeftOption pressed, thus bringing forward the minimized application.

For vanilla Karabiner, I would look into adding a to_after_key_up section.

[:fn :fn nil {:alone :!Ctab :afterup :left_option}]
