When the Reactions option is activated, participants can send an array of emojis to show exactly how they feel about what is being shown. Reactions are available on the "How to participate?" screen and on Slides.

As a presenter, you can decide to enable or disable emoji reactions. This can help to improve focus or to concentrate on what is being presented.

This feature is available to all users.

Emoji reactions are enabled by default. You can disable the option by clicking on the thumbs up in the lower right corner of the presenter screen. You can enable it back the same way.
​

Note that once you enable or disable the option, it will be carried over to the following Slides. You can decide to enable or disable it again anytime a Slide is presented.
