Gestures

Three gestures are configurable, in Settings → Gestures or with config set:

Gesture	Key	Default
Double-tap empty log space	gesture.double-tap	lock
Swipe down on the header	gesture.swipe-down	shade
Swipe up on the prompt	gesture.swipe-up	none (off: it fires by accident easily)

Each value is one of:

• lock: lock the screen,
• shade: pull down the notification shade,
• none: do nothing,
• any command, run as if you typed it.

config set gesture.swipe-up apps -l   # swipe up on the prompt for the app list
config set gesture.double-tap feed read
config set gesture.swipe-down none

lock and shade are also commands you can type, alias or use from a script command.

Locking needs an accessibility service

Android only lets an app lock the screen through an accessibility service. Kolahal ships a tiny one, Kolahal screen lock, that does nothing else. It is declared with canRetrieveWindowContent="false" and scoped to a package that doesn’t exist, so it receives no accessibility events and can’t read the screen. All it does is call the system “lock screen” action.

Enable it with accessibility or setup → Double-tap to lock. Until then, lock prints a tappable line that takes you to the setting.

Other touch gestures

These are fixed:

• Pinch the log to change the text size.
• Tap empty space to show the keyboard.
• Drag sideways across the key bar to move the cursor.
