ACBR is primarily designed to work with keyboard and mouse, but there's gamepad support for some basic controls in the reader:

Right stick (up/down): scroll page (up / down).
Left bumper / Right bumper: go left (change page) / go right (change page).
Left trigger / Right trigger: zoom page out / in.
Left stick (click): toggle full screen.
Right stick (click): switch zoom mode.
BACK button + Y button: go to first (change page).
BACK button + A button: go to last (change page).
START button: open/close a quick menu with buttons to open a gamepad controllable file browser, the history, toggle full screen or quit.
The modals (including the quick menu) and some of the tools (file browser and history) can be controlled with the gamepad:
- Right stick, Left stick or D-Pad: change the currently focused input element (e.g. a UI button).
- A button: interact with the currently focused input element (e.g. click a UI button).
- B button: close the modal/tool (if possible at that moment).
