The built-in file editor lets you read and edit project files directly in Hikari Desktop, alongside your conversation. Open it via File Editor in the menu or press Ctrl+E (requires an active connection).

File Browser

The file browser panel (toggle with Ctrl+B) shows your working directory tree. From it you can:

• Click a file to open it in a new editor tab
• Right-click for context menu options (rename, delete)
• Press Ctrl+N to create a new file

Editor Tabs

Each open file gets its own tab. You can have multiple files open at once.

• Click a tab to switch to that file
• Click × on a tab to close it (Ctrl+W)
• Unsaved changes are indicated with a dot on the tab
• Press Ctrl+S to save the current file

Syntax Highlighting

The editor automatically applies syntax highlighting for a wide range of languages, including:

JavaScript · TypeScript · Python · Rust · Go · Java · C++ · HTML · CSS · JSON · YAML · Markdown · SQL · Shell · PHP · Ruby · Swift · R · TOML · Dockerfile · PowerShell

The editor theme follows your app theme — dark themes use dark editor backgrounds.

Editor Features

• Line numbers, bracket matching, and code folding
• Search and replace (Ctrl+F in most editors)
• Right-click context menu for common operations
• Full CodeMirror keybindings

Working with Hikari

Hikari can read and edit files directly through her tool access — you don't need the file editor open for her to work on files. The editor is most useful for reviewing changes she's made, manually editing files alongside the conversation, or browsing the project structure.
