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 repeatedly at the system key-repeat rate
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)
Swipe down after clearing	restore cleared text	after clearing, keep holding and swipe down to restore the text from before the clear

Avoiding false triggers

To reduce accidental actions:

1. Long-press priority: continuous delete starts after the system long-press duration
2. Distance threshold: a movement must exceed the system touch-slop threshold to count as a swipe
3. Direction clarity: the swipe direction must clearly dominate

Tips

Quickly clear wrong input

Hold backspace → swipe up → release

Undo a mistake

Hold backspace → swipe up to clear → keep holding and swipe down → release

This restores the text from before the clear. You can also hold backspace again and swipe down to undo the last change.

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

Action type	Undoable	Result after undo
Voice recognition commit	✅	removes transcript
AI post-processing edit	✅	restores raw transcript
Manual typing	✅	removes typed text
Character deletion	✅	restores deleted content
Paste	✅	removes pasted content
AI Edit	✅	restores previous text
Clear all	✅	restores cleared content

Undo stack

BiBi Keyboard uses a stack:

[Latest] → Op3 → Op2 → Op1 → [Oldest]
           ↑undo  ↑undo  ↑undo

• Capacity: up to 3 states
