How to make the server talk?

is it possible to type a command into my gmod server cmd to send a message to all the players? if so, what is the command?

Press the talk key (Y by default) and type it in.

You don’t need to send a message using the console, because the chat is easier. I don’t think you CAN send a message using the console now that I think about it.

Type “say [message]” in the console without the quotation marks.

thank you
