How to Reply to Slack Messages on PC or Mac

Method 1 of 2:

Open Slack. You can do this by navigating to your team's URL in a web browser. Or, if you have the desktop application, click it in the Applications folder (macOS) or the Windows menu (Windows).
Select a message. Your messages appear under the 'Direct Messages' header in the left column. Clicking a user's name will open a conversation with that user.
Type a message. To start typing, click the box at the bottom of the screen that says 'Message @username.'
Press ↵ Enter or ⏎ Return. Your message will appear in the conversation.

Method 2 of 2:

Open Slack. You can do this by navigating to your team's URL in a web browser. Or, if you have the desktop application, click it in the Applications folder (macOS) or the Windows menu (Windows).
Select a channel. Channels appear in the left column under the 'Channels' header.
Hover your mouse over a message. Four icons will appear at its upper-right side.
Click the chat bubble icon. It's the second icon in the row. This expands the Threads column on the right side of the window. Threads are easy ways to have side conversations in Slack without taking over the channel.
