How to chat to all

I very rarely see chats too all and don't know how to do it myself. Normally it's SHIFT + ENTER
The following hotkeys have been tried:
- SHIFT + ENTER
- CTRL + ENTER
- ALT + ENTER

You can also chat to all from the normal chat window (which you open by pressing Enter) by adding a * in front of your message. (e.g: *Hi everyone).

The following prefixes are available:

• ; Chat to allies (Default in team game)
• # Chat to enemies (Default in FFA)
• * Chat to everyone

You can utilize the chat by pressing Enter. This will pop-up a dialog bar in which you type your message. Note that everybody can read your message, including the enemy :).

Alternatively you can use chat/trumpet icon (second left of the scroll icon) to pop up the chat window in which you can select those who you want to send a message too.
