Configuration

All settings live in a single global JSON file:

~/.config/e/config.json

Press ⌘, for a graphical settings page covering the common options. The raw file (with advanced sections like agents, snippets, keybindings) can be opened from the command palette via Open Settings (config.json) — it is created on first use.

Panel layout (sidebar_side, agent_side) is read at startup — restart e after changing it. By default the explorer/Git sidebar is on the left and the agent panel on the right; set them to swap sides.

Keybindings

Every action is a named command; rebind any of them in the keybindings section. See Keybindings for the syntax and the full command list.

Themes

e ships with a light and a dark theme. Toggle between them with F8; the choice is saved to config.json. The theme is fully reactive — the whole UI and editor update instantly.

Zoom & word wrap

⌘= / ⌘- change the editor font size for the session; ⌘0 resets to your configured font_size.
⌥Z toggles soft word wrap.

Agents

See AI Agents for the agents section (default agent and the list of configurable agents).

Where things are stored
