Gestures

BiBi Keyboard provides rich gesture interactions to control input, edit text, and manage content efficiently.

Backspace gestures

Backspace supports multiple modes: single-char delete, continuous delete, clear all, and undo.

Basic

Gesture	Action	Notes
Tap	delete one char	standard backspace
Long-press	continuous delete	deletes one char every 50ms
Swipe up	clear all text	deletes all content in the editor
Swipe left	clear all text	same as swipe up
Swipe down	undo	undo last change (up to 3 steps)

Avoiding false triggers

To reduce accidental actions:

1. Long-press priority: press > 500ms to count as long-press
2. Distance threshold: swipe distance must be > 50dp (~8mm)
3. Direction clarity: swipe angle must match the target direction
4. Cancel: moving back to origin cancels the gesture

Tips

Quickly clear wrong input

Hold backspace → swipe up → release

Undo a mistake

Hold backspace → swipe down → release

Typical flow

Voice input → [AI done] → backspace swipe down (undo) → voice input again

Global undo

Besides backspace gestures, the customizable action row can include a global Undo button to undo various text changes.

What can be undone
