Collapse a message
Zulip allows you to collapse messages by hiding their contents to reduce message clutter.
Hover over a message to replace the message's timestamp with its message actions, represented by three icons. From the icons that appear, select the down chevron () icon to reveal an actions dropdown.
Click on the Collapse option from the actions dropdown to collapse a message.
To uncollapse a message, click the [More...] hyperlink near the bottom of a collapsed message.
