Zedコードエディタの使い方：ダウンロード、最初のプロジェクト、ショートカット、AIパネル

Zedを入れ、リポジトリを開き、ショートカットを覚え、Assistantで最初のAI対話を行う。

Switching from VS Code or JetBrains, the scary part is installing something and not knowing the next click. Zed is a GPU-accelerated code editor built in Rust, focused on low-latency editing, built-in collaboration, and an AI assistant panel.

People searching Zed エディタ ダウンロード ショートカット AI アシスタント usually need four outcomes: install from the official site, open a first project folder, learn core shortcuts, and send a first prompt in the Assistant panel. Steps follow zed.dev documentation.

Who Zed is for

01

Developers who want snappy local editing

Scrolling large repos, completions, and multi-cursor edits prioritize responsiveness; the project advertises a GPU-oriented input and render path.

02

Teams that want AI without leaving the editor

The Assistant panel can answer about the current file or selection; inline flows may insert suggestions depending on your version—check official AI docs.

03

macOS / Linux daily drivers

Platform builds are listed on the Download page; confirm support before switching machines.

Download and install

  1. 1

    Use the official download page

    Visit https://zed.dev/download. Avoid third-party mirrors so signatures and update channels stay trustworthy.

  2. 2

    macOS: install from .dmg

    Open the disk image and drag Zed into Applications. If Gatekeeper blocks the first launch, allow it under System Settings → Privacy & Security. Pick Apple Silicon or Intel builds as offered on the site.

  3. 3

    Linux: follow distro instructions

    The site typically ships .tar.gz archives or install scripts. Add Zed to your PATH or desktop entry per the docs; library dependencies are listed on Download.

  4. 4

    First launch and updates

    Zed can check for updates through its built-in flow. Staying reasonably current helps LSP and AI fixes. Signing in to a Zed account is required for some Assistant features—see below.

Open your first project

Open a folder, not an orphan file, so language servers and Git status work.

File → Open Folder… → pick your repo root

# Or from the command palette
Cmd+Shift+P (macOS) / Ctrl+Shift+P (Linux)
Type: open folder / new project (exact entries vary)

The file tree sits on the left, editor in the center, terminal panel at the bottom. Git repos show changes; language mode is inferred from extensions and can be adjusted in the status bar.

Core shortcuts (macOS; use Ctrl on Linux)

ShortcutActionUse case
Cmd+Shift+PCommand paletteWhen you cannot find a menu item
Cmd+PQuick open fileJump across large trees
Cmd+Shift+FProject searchFind symbols or strings
Cmd+BToggle sidebarMore editor width
Cmd+`Terminal panelTests and git
Cmd+K Cmd+SKeyboard shortcutsLookup or rebind keys

Full lists: command palette → keyboard shortcuts, or docs.zed.dev Keyboard Shortcuts. Many defaults resemble VS Code; see Zed’s migration guide if you are switching.

AI Assistant panel basics

  1. 1

    Sign in to Zed

    Some Assistant capabilities require an account (Sign in in the panel or menu). Models, quotas, and paid tiers are defined on Zed’s pricing/docs pages—do not assume everything is free.

  2. 2

    Open the Assistant panel

    Use the sidebar icon, command palette (assistant / panel), or the shortcut documented for your version. The panel scrolls independently beside the editor.

  3. 3

    Ask with selection context

    Highlight code before prompting so the assistant sees context—explain a function, sketch tests, or turn logs into a checklist. Review output before committing.

  4. 4

    Inline edits when available

    Some builds support inline generate/edit at the cursor; entry points live in the AI docs. Preview diffs before accepting changes.

Zed is an editor, not CI or hosting. AI suggestions do not replace review; never paste secrets into Assistant chats.

Language server idle
Open the repo root, not a single file; confirm the language is supported and LSP is enabled in settings.
Shortcut clashes
Search commands in Keyboard Shortcuts and rebind; desktop environments may steal keys.
Assistant disabled
Sign in, check network/proxy settings per docs, then Help → View Logs for errors.

For whiteboard or voice sync, open a browser room from the wbroom homepage — create and join a room.

Questions worth checking

How is Zed different from VS Code?

Zed is a native app emphasizing latency, collaboration, and built-in AI; VS Code has a larger extension marketplace. Pick based on whether you need Zed’s path or an existing VS Code toolchain.

Can I code offline?

Local editing and cached LSP can work offline; Assistant typically needs network—see official docs for your version.

Where are settings stored?

JSON settings via command palette → Default/User Settings; paths and merge rules are in Configuring Zed on docs.zed.dev.

Is Windows supported?

Check zed.dev/download for the current platform list before installing; this guide focuses on macOS and Linux.
