# Reacting to a message ## Add the first reaction to a message To react to a message in a channel or thread, hover over it with your mouse: the "add a reaction" button will appear in the form of a smiley icon. Click on it to open the emoji keyboard! Repeat the action as many times as you like to add several reactions. {% hint style="info" %} The member whose message you are reacting to will not receive a notification. {% endhint %} When you move your mouse over a reaction, the list of members who have reacted is displayed! ## Add other reactions If a reaction has already been added to a message, you can add another reaction: * By clicking on the emoji of the reaction already added to add the same reaction. * By clicking on the add reaction button that appears to the right of the already existing reactions to the message.
