The fork shipped renamed binary/bundle but the product name "Zed" was still
shown everywhere in the UI. Rename the display name to "Joule" (tagline
"Energy-metered agentic coding") while preserving every load-bearing reference.
Display renames (105 .rs files): release_channel display_name, welcome +
onboarding + ai_onboarding, macOS app menu (About/Hide/Quit), window titles,
About panel, settings UI, notifications, update/collab messages, system specs.
Bundle display name (crates/zed/Cargo.toml) -> "Joule" so CFBundleName / the
menu-bar name and the .app are "Joule" (identifier science.transaction.AgentJoule
and the agent-joule binary are unchanged).
Docs (223 .md): product prose Zed -> Joule, fence-aware (code blocks untouched).
Embedded assets (12 JSONC): // comments only.
Legal (4 files): product -> Joule, entity "Zed Industries, Inc." -> "Transaction
Science, Inc.", domain zed.dev -> openie.dev. NOTE: these are structurally Zed's
inherited terms and need a real legal review, not just a rename.
Deliberately PRESERVED (renaming would break the app): font aliases ("Zed Plex
Sans"/".ZedMono" in text_system + assets), HTTP header names (X-Zed-Predict-*),
zed:: action ids, app/bundle identifiers (dev.zed.Zed*, Zed-Editor-* product ids),
zed.dev URLs, ZED_* env vars, crate/package names, "Zed Industries" in non-legal
attribution, and the {zed,Zed} config-dir glob.
Signed + notarized + stapled as Joule.app, installed to /Applications, verified
(Gatekeeper: Notarized Developer ID, FH93XC2VRR). Caveat: test-code string
literals were renamed too, so some `cargo test` assertions may need updating.

title: Finding and Navigating Code - Joule description: Navigate your codebase in Joule with file finder, project search, go to definition, symbol search, and the command palette.
Finding & Navigating
Joule provides several ways to move around your codebase quickly. Here's an overview of the main navigation tools.
Command Palette
The Command Palette ({#kb command_palette::Toggle}) is your gateway to almost everything in Joule. Type a few characters to filter commands, then press Enter to execute.

File Finder
Open any file in your project with {#kb file_finder::Toggle}. Type part of the filename or path to narrow results.
Project Search
Search across all files with {#kb pane::DeploySearch}. Results appear in a multibuffer, letting you edit matches in place.
Go to Definition
Jump to where a symbol is defined with {#kb editor::GoToDefinition} (or Cmd+Click / Ctrl+Click). If there are multiple definitions, they open in a multibuffer.
Go to Symbol
- Current file: {#kb outline::Toggle} opens an outline of symbols in the active file
- Entire project: {#kb project_symbols::Toggle} searches symbols across all files
Outline Panel
The Outline Panel ({#kb outline_panel::ToggleFocus}) shows a persistent tree view of symbols in the current file. It's especially useful with multibuffers for navigating search results or diagnostics.

Tab Switcher
Quickly switch between open tabs with {#kb tab_switcher::Toggle}. Tabs are sorted by recent use—keep holding Ctrl and press Tab to cycle through them.
