Changing the command+W "Close Window" keyboard shortcut on the macOS client

[Drillbro Dankins]

Whenever I use steam remote play from a macOS machine, I always accidentally hit command+W, because command is right next to the space bar, and W is usually the forward movement button. This is super frustrating because it immediately shuts down the game.

Does anyone have any ideas for how to change the keyboard shortcut for "Close Window" for the steamstreamingclient window?

I can change the shortcut for Steam itself easily enough, but the actual streaming client window doesn't seem to inherit the shortcuts, and there's no standalone app to associate keyboard shortcuts with. Maybe some magic "defaults write" command?

Never mind, I figured it out. The streaming client application is located at ~/Library/Application Support/Steam/Steam.AppBundle/Steam/Contents/MacOS/streaming_client and uses the plist domain com.valvesoftware.steam.streamingclient, which means you can set keyboard shortcuts using defaults write.

I disabled the "Close Window" shortcut, and set the "Quit" shortcut to option+F4 like so:

defaults write com.valvesoftware.steam.streamingclient NSUserKeyEquivalents '{Close="\U200b";"Quit steamstreamingclient"="~\Uf707";}'
