The Button Changed Driving Me Crazy

Hey, thanks for the feedback. I get the frustration. This change in Cursor 2.3 broke the workflow for a lot of users.

The button to toggle chat was removed on purpose in favor of customizable layouts. Here’s how to hide chat now:

Quick fix:

  • CMD+ALT+B (or CTRL+ALT+B on Windows) to toggle the chat panel
  • CMD+E to toggle the Agent layout

Alternative (if you want the Agent sidebar instead of fullscreen):

  • Gear icon (top right) > select Editor layout
  • CMD+I to toggle the Agent sidebar

The gear icon also lets you set up and save a custom layout.

I know hotkeys aren’t a replacement for the button you’re used to. If you want to share feedback about this change, the team is collecting UI comments here: [Megathread] Cursor layout and UI feedback
