Instructions for name and messages

Best regards and I hope this is good.

I would like to replace the placeholder where the person puts their name since it is in English to place it in Spanish

Similarly, in the message box, I would like to place a placeholder that indicates that there is a place to put your message and send it with enter.

Thank you very much for helping me.

Cordial greetings and thanks for responding.

Could you please tell me the file and the route where the string SHOUT_NAME is located?

In the same way, could you please indicate me in the area of the message box, how can I place a text that indicates that there are messages that can be placed in SHOUT_NAME style, but SHOUT_MESSAGE?

The previous thing is because I wish that the users have some small indication that in that picture messages are sent and they are sent with the enter key.

Thank you very much for your kind cooperation.

Hello and thanks for replying, the first point in relation to SHOUT_NAME is clear.

Regarding the second point:

"I'm not sure what you mean by your second point.
Do you wish to have a placeholder for users that says "Enter to submit" so they know how to submit a message?

In the first message of my post attach capture image of what I want, If there is a field to indicate to place a name, I want to implement a field to place the word "message" in the message box to indicate to the user that he should put a message and send it with enter, in the image leave that highlighted.

Thanks for the help.
