+CLI and TUI preferences are separate from OpenCode's server and project
+configuration. They live in the global `~/.config/opencode/cli.json`, or
+`$XDG_CONFIG_HOME/opencode/cli.json` when `XDG_CONFIG_HOME` is set. There is no
+project-local CLI configuration. Most preferences can also be changed from the
+TUI by pressing `Ctrl+P` and selecting **Open settings**.
+
+Fetch the full [CLI configuration guide](https://opencode.ai/v2/docs/cli/config)
+before editing `cli.json`. It covers terminal-only settings such as themes,
+keybindings, terminal plugins, scrolling, attention alerts, diff presentation,
+and terminal integration. Do not put these settings in `opencode.json(c)`.

+### [Keybinds](https://opencode.ai/v2/docs/cli/keybinds)
+
+Configure keybindings under `keybinds` in `cli.json`. The leader key is the
+`keybinds.leader` entry; leader timing is configured separately under
+`leader.timeout`. Bindings can use a string, an array of strings, or an object
+when event behavior such as `preventDefault` is required. Disable a binding
+with `"none"` or `false`.
+
+Never guess a command ID, default binding, or accepted key syntax. Fetch the
+full [keybind reference](https://opencode.ai/v2/docs/cli/keybinds), which lists
+the current IDs and defaults, before answering or editing a binding.
