Add mission control to focus for app switcher

[thetomcraig]

This adds functionality for application switching on MacOS. The actual equivalent on MacOS is the Application Switcher (Command + Tab), but there is no built in way for this, to be persistent on screen with a single hot key. The best alternative is Mission Control, which will show all of the open windows.

The way to do this without depending on the activation keystroke not being reset is using talon.mac.dock; I have this implemented as user.dock_send_notification("com.apple.expose.awake").

I had not submitted this change for incorporation into community as there is no way to navigate Mission Control from the keyboard or via accessibility. I guess it might be useful to people who use an eye tracker or another pointing device?

Update — at the community backlog session we decided to go ahead and get this merged. You can grab my code from https://github.com/nriley/talon_community/tree/nriley/apps/dock.

+1, +1 to also using the dock notification API if it works instead of the key shortcut, since it's possible people would redefine it

[thetomcraig]

So are we thinking that using that API would be more stable than the built in keystroke?

Also, @nriley now I understand what you're saying about not being able to navigate Mission Control with the keyboard. But I do find using with an eye tracker pretty nice 🙂
