How to Fine-tune your iBooks experience
Go full(ish) screen 1
If any app naturally suits fullscreen mode, it’s iBooks. However, if you want the clock visible while reading,
å- click the Zoom button (the green one) to make the window fill the rest of the display for a better experience.
Change the theme 2
If you can’t read a book‘s text comfortably, click the appearance button ( AA) to adjust size, font, and page and text colors. For a faster way to adjust the text size multiple times in succession, press ç+= or ç+-.
Take things further 3
Unsure about a word’s meaning? Double-click it for its definition. Want to scribble down some thoughts? Highlight a block of text then choose a color, and add a note; click the note icon near the top left of iBooks to view your notes.
