+Failed setup retries on the next activation, or on a dock update for eager scripts. Setup is cached per RPC connection, dock and import descriptor. Action clicks always execute again, except for a [toggle action](#toggle-actions).
+
+### Toggle actions
+
+Set `toggle: true` on an `action` entry to make it an on/off tool, such as an in-page element picker. A click turns it on and a second click turns it off. While it is on:
+
+- the dock button shows as active (`current.isActive` is `true`);
+- the selected dock stays selected, and an open panel is hidden until the tool turns off;
+- `Escape` turns it off in the reference hub UI.
+
+The script sets up once and drives the tool from `entry:activated` / `entry:deactivated`. Call `docks.setActionActive(id, false)` when the tool is done, which brings the hidden panel back. Selecting another dock, or `switchEntry(null)`, also turns the tool off, and then the panel stays as the new selection leaves it.
+
+```ts
+// Dock entry: { type: 'action', toggle: true, action: { importFrom } }
+import type { DockClientScriptContext } from '@devframes/hub/client'
+
+export default function setup(ctx: DockClientScriptContext) {
+  const id = ctx.current.entryMeta.id
+  ctx.current.events.on('entry:activated', () => {
+    startPicker({ onPick: () => ctx.docks.setActionActive(id, false) })
+  })
+  ctx.current.events.on('entry:deactivated', () => stopPicker())
+}
+```
