It would be great to have tips for TTS during the game's loading screens.

The two places I can think of where these tips would show up is during the first loading of the game and while loading to join a server. I came up with this idea cause i read that you can hold alt while box selecting to select even locked items, something I didn't know. There's a number of little controls that are pretty hidden that would be great to show in simple little text lines.

You could add a message at the bottom of the main menu too. Please feel free to comment with the sort of tips that could be part of the list.
