1. Sending messages to multiple people - Message broadcasting
Earlier there was no option to send messages more than one person at a time, without creating a group. But now, WhatsApp has added this new feature where you can send a message to multiple persons. Remember, you cannot forward a message to multiple people. It has to be your own message and not the forwarded message. If you want to broadcast a forwarded message, then you can copy and send it to multiple persons
Follow these steps to broadcast a message to multiple persons.
You will find a menu item called New Broadcast, click on it. In the next screen, you will get an option to chose the contacts to which you want to broadcast a message. Select the contacts and click on the tick mark at the bottom to go the compose screen.
2. Change the way ENTER key works
In most cases when you press the ENTER key on your keyboard, it takes you to the new line. But in WhatsApp, you can configure it to act as a SEND button. That means, whenever you press the ENTER key, the message, which is already composed will be sent. You can configure this in the CHAT settings.
Under the CHATS menu, click on the 3 dots. Then select Chats
