 ## ⚙️ Configuration
 
-> **Note**: The keymap configuration structure has been updated. Old keymaps (`keymap.global` and `keymap.window`) will be mapped to the new format (`keymap.editor`, `keymap.input_window`, `keymap.output_window`) but you should update your config to the new format. See [Keymap Configuration](#keymap-configuration) below for details.

 ### Responding to Permission Requests
 
-- **Respond via keys:** In the input window press `a` to accept once, `A` to accept and remember (accept all), or `d` to deny. These window keys are configurable in `ui.keymap.window.permission_*`.
-- **Global keymaps:** There are also global keymaps to respond outside the input window: `<leader>opa` (accept once), `<leader>opA` (accept all), `<leader>opd` (deny). These are configurable in `keymap.global.permission_*`.
+- **Respond via the dialog:** Focus the Opencode window, move with `j`/`k` or arrow keys, then confirm with `<CR>`. Number shortcuts `1-3` also work for the visible options.
+- **Command:** Use `:Opencode permission accept`, `:Opencode permission accept_all`, or `:Opencode permission deny`. You can pass an index to target a specific queued permission.
 - **API:** Programmatic responses are available: `require('opencode.api').permission_accept()`, `require('opencode.api').permission_accept_all()`, `require('opencode.api').permission_deny()` which map to responses `"once"`, `"always"`, and `"reject"` respectively.
 - **Behavior:** `accept once` allows the single requested action, `accept all` grants persistent permission for similar requests in the current session, and `deny` rejects the request.
