i think it would be cool to have all of those pop up commands in the options to be able to use just 1 key to do each, that way the user could bind a key to say, join squad or requesting pickup or however or whatever that user wanted to just have for 1 key, or more.
I think that the more hotkeys, the better, especially for comm, but this might be something that needs to wait untill we can set our key configs ourselves.
