 ## Driving the VM's screen
 
-- Click the `tart` window's title bar first: the VM takes clicks and keys only while its window is the key window.
-- Keys reach the VM without their modifiers through hands, so Shift, Cmd and symbols typed with `type` or `key` arrive wrong. Type only lowercase text and plain symbols there, and do the rest over SSH.
-- Scrolling doesn't reach the VM; drag the scroll bar instead.
+- Start each `act` with a click on an empty part of the VM's screen, not its title bar: the VM takes clicks and keys only after a click inside it.
+- `tart run` in a terminal runs until the VM stops, and Ctrl-C in that terminal shuts the VM down.
 - `screencapture` over SSH fails for lack of Screen Recording in the VM; capture the `tart` window from the host with hands.
 - Check `screen_list` before acting: another task's `tart` window can sit exactly on top of yours.
