Open the Launcher
Do one of the following:
- In Card view, tap the Launcher icon at the right end of Quick Launch.
- In Card view, flick up on the gesture area.
- Press the Menu or Home key, if your device has one. On some keyboards these keys do something else.
If an application fills the screen, display Card view first.
To close the Launcher, flick up on the gesture area again, or tap the Launcher icon.
Checked against the LuneOS code and installed apps. Nobody has tried these steps by hand yet, so tell us if something differs.
