+### `noop` {#manager.noop}
+
+If you want to disable certain preset keybindings without rewriting the entire `keymap`, you can use the virtual `noop` command.
+
+For example, to disable the default keybinding of <kbd>g</kbd> ⇒ <kbd>c</kbd>, use:
+
+```toml
+[[manager.prepend_keymap]]
+on = [ "g", "c" ]
+run = "noop"
+```
+
+Or, if you prefer an array style:
+
+```toml
+[[manager.prepend_keymap]]
+on = [ "g", "c" ]
+run = [ "noop" ]  # The array can only have one element and must be "noop"
+```
+
+The disabled keys won't trigger any actions when pressed and won't show up in the `which` component.
