Keep your books privateEvery Kindle allows you to set a pass code to keep your reading preferences private. All you need to do is go to Settings > Device Options > Device Passcode and follow the instructions.
Improve your vocabularyWordWise shows you the meanings of difficult words right on top of them on the page. To enable it, open the book, tap the top side of the screen, tap the options button on the top right, and select WordWise. The number of hints to be shown on a page is adjustable with a slider. You can also use the Vocabulary Builder that keeps a track of all the words you've looked up while reading and even allows you to try flashcards on those.
Keep track of timeIt is easy to lose yourself in a good book. To avoid that from happening, you can enable the clock while reading a book to keep a track of time. To do that, tap the top side of the screen, and go to Page Display > Font & Page Settings > Reading tab. Here, you can toggle ‘Show Clock While Reading’ to keep track of time.
Use it in landscape modeOne of the first restrictions that strike anyone new to e-books is viewing only one page at a time, in portrait orientation. However, there's a way around that by using your Kindle in landscape mode. The exact steps and features can vary between models, but the general idea is to open a book, go to Page Display and then explore the settings there to find the right options for you.
Upload your own fontMany times, you won't be satisfied with the feel of a book just because the font isn't right. In such a case, you can upload your own font for the Kindle to use. To do that, connect your Kindle to a computer with a USB cable, browse the Kindle directory to find ‘Fonts’ folder, and copy OTF or TTF font files in the fonts folder.
