How can catchall bind be used to prevent passing stray keys to applications

[anna-s-h]

I want to have a modal system where in my window managing mode, keys not used for window management don't get passed to applications. According to the wiki is possible, but the only example given is for switching out of the mode. I tried making it switch to the mode it's already in but the inputs were still being passed to applications.

You can also define a keybind via the special catchall keyword, which activates no matter which key is pressed. This can be used to prevent any keys from passing to your active application while in a submap or to exit it immediately when any unknown key is pressed:

    #Enter workspace mode
      bind = $mainMod, S, submap, wsmap
      submap = wsmap

    #Eat stray inputs
    #currently doesn't work?
      bind = , catchall, submap, wsmap

I was dumb and using the wrong version. This isn't actually an issue.
