Closes https://github.com/zed-industries/zed/issues/37087 This PR adds an icon button to the footer of the message editor enabling to trigger and interact with the @-mention completions menu with the mouse. This is a first step towards making other types of context you can add in Zed's agent panel more discoverable. Next, I want to improve the discoverability of images and selections, given that you wouldn't necessarily know they work in Zed without a clear way to see them. But I think that for now, this is enough to close the issue above, which had lots of productive comments and discussion! <img width="500" height="540" alt="Screenshot 2025-11-11 at 10 46 3@2x" src="https://github.com/user-attachments/assets/fd028442-6f77-4153-bea1-c0b815da4ac6" /> Release Notes: - agent: Added an icon button in the agent panel that allows to trigger the @-mention menu (for adding context) now also with the mouse.
Zed Icons
Guidelines
Icons are a big part of Zed, and they're how we convey hundreds of actions without relying on labeled buttons. When introducing a new icon, it's important to ensure consistency with the existing set, which follows these guidelines:
- The SVG view box should be 16x16.
- For outlined icons, use a 1.2px stroke width.
- Not all icons are mathematically aligned; there's quite a bit of optical adjustment. However, try to keep the icon within an internal 12x12 bounding box as much as possible while ensuring proper visibility.
- Use the
filledandoutlinedterminology when introducing icons that will have these two variants. - Icons that are deeply contextual may have the feature context as their name prefix. For example,
ToolWeb,ReplPlay,DebugStepInto, etc. - Avoid complex layer structures in the icon SVG, like clipping masks and similar elements. When the shape becomes too complex, we recommend running the SVG through SVGOMG to clean it up.
Sourcing
Most icons are created by sourcing them from Lucide. Then, they're modified, adjusted, cleaned up, and simplified depending on their use and overall fit with Zed.
Sometimes, we may use other sources like Phosphor, but we also design many icons completely from scratch.
Contributing
To introduce a new icon, add the .svg file to the assets/icon directory and then add its corresponding item to the icons.rs file within the crates directory.
- SVG files in the assets folder follow a snake_case name format.
- Icons in the
icons.rsfile follow the PascalCase name format.
Make sure to tag a member of Zed's design team so we can review and adjust any newly introduced icon.
