we pretty much know OOO won't implement any form of voice chat. so basically, this idea to have a list of pre-made quick phrases or responses to reduce the time it takes to type the whole thing out normally
yes there is the fact that people will spam this so make them have a 3-5 second delay between each usage
so like some would be
1. Mineral deposits here.
2. I have the key.
3. I'm under attack need help!
4. Please revive me!
5. Let's do this!
6. I'm not leaving without my totem buddy!!
If you have a keyboard with a Numpad try mashing the the buttons. You'll find that a few useful phrases are already linked to them. You can even change the keybinds is you want.
