📲 How to Change Scrolling Mode
Open A1 PDF Editor on your iPhone or iPad.
Open any PDF document.
Tap the View Settings icon (usually found in the top right or bottom menu).
Select Scrolling Direction.
Choose:
Vertical Scrolling – Scroll up and down to navigate pages.
Horizontal Scrolling – Swipe left or right to move between pages.

The app remembers your selected mode, so you won’t have to set it every time.
Horizontal scrolling is great for presentations or side-by-side reading.
Vertical scrolling is ideal for continuous reading like books or lengthy articles.
