## User interface

- To show the TOP MENU or BOTTOM MENU you can click the indicated zones. You can click or swipe down the upper zone to show the TOP MENU.
- The STATUS BAR zone can be used to cycle between STATUS BAR items if one item is visible. This will also hide and show the STATUS BAR if you tap enough times.

## User interface tips

- You can change the interface language using:

> TOP MENU ➔ ➔ Language

- If you tap and hold on an option or menu item (font weight, line spacing etc.), you can set its value as DEFAULT. The new value will only be applied to documents opened from now on. Previously opened documents will keep their settings. You can identify default values as a STAR in menu or as a black border around indicators as seen below:

- You can see explanations for all items on the BOTTOM MENU by tapping and holding the name of the option. This is also available for most of the TOP MENU menu items.
- You can CLOSE full screen dialogs (History, Table of Contents, Bookmarks, Reading Statistics etc.) by swiping down
- SCREENSHOTS can be taken by touching opposing corners of the screen diagonally at the same time or by making a long diagonal swipe

- In dialogs containing adjustment arrow buttons like the one above, you can tap and hold on arrow buttons to increase / decrease the value in bigger increments
- You can CLOSE this type of dialog (non-full screen) by tapping outside of the window. You can MOVE this type of dialog by holding the window title and dragging
