Features

A breadcrumb trail is displayed at the top of multi-buffers and singleton buffers with the path of the file containing the cursor along with a summary of the containing syntax nodes. This can be especially helpful in multi-buffers or within large functions.

To install the zed command line tool, select Zed > Install CLI from the application menu. Then you can type zed my-path on the command line to open a directory or file in Zed. To use Zed as your $EDITOR to edit Git commits etc, add export EDITOR="zed --wait" to your shell profile.

Whenever you see a lightning bolt next to the gutter, it means a code action is available for the current cursor location from the language server. You can click the lightning bolt or press cmd-. to reveal available actions.

Code actions affecting multiple files will present the results of the action in a multi-buffer. To undo the action, simply hit cmd-z in the multi-buffer, although we don't yet support undoing file-system changes. To save the results of a multi-file code action, just save the multi-buffer.

Adding contacts

You can add a contact from the collaboration menu, deployed from the icon in the upper right corner of the window, or by pressing cmd-shift-c and then clicking the add button to the right of the search box.

If you are trying to collaborate with someone who hasn't started using Zed yet, get them to download Zed and sign in, then you can add them.

Sharing a project

You'll see all your online contacts in the collaboration menu. Searching or clicking on them will send a request to start a call and share your current project with them. They will recieve a notification to join your call.

This will open a new window containing their project. Once you have joined the call, your zed windows will show the participants of the call next to your icon in the top right. Grayscale participants are in the call but currently viewing a different project. Non-grayscale participants are in the same project as you.

Projects not yet shared with the call will have a share button in which will enable others to join your project.

Our goal is to eliminate the distinction between local and remote projects as much as possible. Guests can open, edit, and save files, perform searches, interact with the language server, etc.

Following a collaborator

When you join a project, you'll immediately start following the host as they move within and between files. This is represented by a border around the editor.

You automatically stop following whenever you move the cursor or edit. To start following again, you can click on a collaborator's avatar or cycle through following different participants by pressing ctrl-alt-cmd-f.

Following is confined to a particular pane. When a pane is following a collaborator, it is outlined in their cursor color. This pane-specific behavior allows you to follow someone in one pane while navigating independently in another, and can be an effective layout for some styles of collaboration.

You may switch projects via the collaboration menu which shows current participants and any projects they may be sharing.

Screensharing

Sometimes you must go beyond code when collaborating, like looking at a website or a drawing. Zed's built-in screen-sharing allows you to share your screen without additional tools easily. Click the "Share Screen" button in the upper right to share your screen.

Once you start sharing your screen, the other participants in the call can see everything on your screen. This can be helpful for collaboration, troubleshooting, or simply sharing information with others.

Always be cautious when screen sharing– avoid accidentally exposing personal information, passwords, or secrets.

Currently, Zed only supports sharing your entire screen.

If there's one default key binding to remember, it's cmd-shift-p. This deploys the command palette, which is a gateway to much of the other functionality that Zed offers and a convenient tool for learning key bindings.

Available commands depend of what is focused. For example, if you focus the project panel, you'll see project panel: add file in the command palette, but you won't see that command if an editor is focused.

Buffer diagnostics

When your perfectly-imperfect self introduces an error or warning into the code, you'll see it indicated with a wavy underline. If you place your cursor within the underlined text, you'll see the first line of the error in the status bar.

For more details, you can expand the error by hitting f8. You can cycle through all errors in the current buffer with f8 and shift-f8 to cycle backwards. Once you fix the error, you'll see it grayed out, at which point you can press escape to dismiss it.

Project-wide diagnostics

Zed displays the number of errors and warnings that exist across your entire project in the status bar at the lower left corner of the workspace. If you click this indicator or press cmd-shift-M, you'll open the project diagnostics multi-buffer.

This multi-buffer contains an excerpt for every error in your project, and its contents will update as you fix errors and save. Sometimes the language server reports multiple errors for the same piece of code.

We've chosen to be faithful to the output of the compiler and present an excerpt for each error, even if this means you'll sometimes see multiple excerpts for overlapping sections of a file.

As with any multi-buffer, you can jump to the location of your cursor in an ordinary singleton buffer by pressing alt-enter. Don't forget you can navigate back to the multi-buffer with ctrl-- after making your fix.

There is one special pane called the dock which can be opened and dismissed while keeping its contents.

It can be fetched and dismissed with shift-escape. By default it opens with a terminal but any editor or tab may be dragged into it.

The dock may be anchored to the right, bottom, and as a modal via the dock anchor menu in the top right of its pane or by the associated key bindings.

Common dock use cases:

• easily fetchable persistent terminal
• quick reference information for documentation pages or related source files
• a place for the diagnostics page

If an item in the dock is focused via a key binding such as the diagnostics item via cmd-shift-m, the dock will be revealed and focused making it convenient for those global singleton tabs.

Syntactic Editing

To fold and unfold code based on the syntax tree, press cmd-alt-{ and cmd-alt-}.

To grow and shrink the selection based on the syntax tree, press alt-up and alt-down.

To jump to the nearest enclosing bracket or its matching counterpart, press ctrl-m.

Multi-cursor editing

You can create multiple cursors/selections via the mouse by alt-clicking/dragging.

To add a new selection above or below the current, press alt-cmd-up or alt-cmd-down.

To select the word under the cursor, then the next matching piece of text, press cmd-d. To skip a word, press cmd-d to select it, then cmd-k cmd-d to select the next. To undo your selection, press cmd-u.

To fuzzy-search all files in your project by path, use the file finder, which you can toggle with cmd-p.

When you first open a file in a specific language, Zed will download and start the appropriate language server if it's supported. Rust remains our primary focus in the short term, but Zed currently has hard-coded language server support for:

• Rust
• TypeScript
• Python
• and more

The ability to connect Zed with an arbitrary language server is under active development.

Multi-buffers are edited much like ordinary buffers, but they contain editable excerpts from multiple different files. They're used in multiple ways in Zed. In the case of project search, you'll see an excerpt with a few context lines surrounding every match.

Multi-buffers allow you to perform multi-cursor edits that span multiple files. When you save a multi-buffer, every excerpted file is saved.

To jump to the cursor's location in a dedicated buffer for the excerpted file, press alt-enter. If you have multiple cursors, a tab will be opened for the location of each cursor.

Code Navigation

You can jump to the symbol definition under your cursor with f12 or by cmd-clicking on the symbol.

Once you've jumped to a definition or performed any non-local navigation, you can use the navigation history to navigate backward with ctrl-- and forwards with ctrl-shift-_. The navigation history is intentionally scoped per-pane, so we'll never switch your focus to another pane when navigating forwards and backwards.

Find all references

To find all references to the symbol under your cursor, press alt-shift-f12. References will be displayed in a multi-buffer with excerpts for each occurrence, similar to how project-wide search works.

To use the language server to search for a symbol across the project, press cmd-t.

Buffer Navigation

Within ordinary buffers, there are a few ways to navigate. You can search a buffer with cmd-f, but we don't currently support replace.

You can also jump to a specific line with ctrl-g.

The most powerful way to navigate within a buffer is Zed's outline view. When you press cmd-shift-O with an editor focused, Zed presents a summary of the file based on the syntax tree. This is useful in a few ways.

It can be a good way to understand the layout of a file, which can be helpful when browsing code or when deciding where to insert a new definition. When you first open the outline view, Zed always highlights the entry closest to your current location within the file.

You can also use it to quickly jump to a named definition in a file by fuzzy searching. The file order is preserved, but the best match to your query is automatically selected.

A cool hidden feature is that when your query contains a space, we expand the search to match on contextual keywords. So in Rust, you could type select to search for any definition whose names matches the word select. But you could type pub fn select to search all public methods or functions matching the word select. You could also type pub fn to simply see all public functions or struct to see all struct definitions.

The project browser is the panel at the left that displays the contents of your project as directory trees. You can toggle focus to and from the project browser with cmd-shift-e. You can toggle its visibility with cmd-b. It can also be toggled with the file tree icon in the lower left corner of the workspace.

Every Zed window corresponds to a project, and you can add multiple folders or even individual files to a project. Project-wide interactions apply to all folders that you add.

For now, projects aren't persistent. Once you close the window, your project disappears.

Search your entire project with cmd-shift-f. This pulls up a dedicated tab in which to search and display your results. You can make your search case-sensitive, regular-expression-based, and apply to whole words only. We don't yet support restricting the search to specific paths.

To create multiple project searches, confirm your search query with cmd-enter instead of enter. This will open the results of this new search as an additional tab and leave the old results tab in place.

Search results are presented in a multi-buffer, which is one of Zed's unique features.

To perform a rename refactoring, place your cursor on the symbol you'd like to rename and press f2.

If the rename impacts multiple files, you'll see the results in a multi-buffer.

To split a pane, press cmd-k followed by an arrow the direction you want to split. So to split the current tab to the right, it's cmd-k right. To cycle focus among different panes, press cmd-k cmd-right to cycle forwards or cmd-k cmd-left to cycle backwards.

Panes can't currently be resized (#216). Until panes can be resized you can use the dock as an impromptu resizable pane.

Zed comes with an integrated terminal emulator that uses Alacritty as its backend.

You can open the terminal with ctrl-` or by clicking the + icon on the right side of the tab bar.

Terminals can also be created and used anywhere a buffer tab can.

Zed ships with a number of common editor themes. Themes will continue to be added to and improved.

In the future users will be able to create, download and load external themes. See Themes – Docs for more info.

Choosing a theme

Toggle select a theme, press cmd-k cmd-t. We don't currently support user-defined themes, but we've tried to include some nice default options.

Vim mode is a work in progress

Fundamental parts of the Vim mode experience are still missing. We will continue devloping it and will make an annoucement when we consider it ready for full time use.

Enabling Vim mode

You can enable Vim mode by adding vim_mode: true to your settings.json.

More about settings in Configuring Zed.

Please report issues you encounter while using Vim mode.

Vim mode quality

We expect our Vim key bindings to be standard. To ensure the quality of our Vim bindings, we currently test Zed's Vim mode output against Neovim itself.
