Switching AC Mode

To simplify the keyboard layout, we have merged the C (clear current input), AC (clear all), and AC (no confirmation) buttons.

• Default is C key: Tap to clear the number you are currently typing.
• Swipe to switch modes: Swipe on the C button to switch between AC and AC (no confirmation) for more efficient operation.

Dragging Tips

• Hide keyboard when dragging: The keyboard will automatically hide when you drag a number or expression, making the dragging operation clearer and more convenient.
• Prevent accidental touches:
  • Dragging expressions: You need to long-press the equals sign for 300 ms to drag the entire expression.
  • Dragging numbers: You need to select the number first, and then you can drag it.
• Pre-calculation result drag restriction: To ensure calculation accuracy, the preview result of an expression (the semi-transparent number) cannot be dragged into other formulas.
