How to Take Notes on an iPad (7 Steps)

Tap 'Notes' on your home screen to launch the app.
Tap the 'Plus' sign on the upper right corner of your screen to create a new notes page. You'll see an on-screen keyboard appear at the bottom and your cursor blinking on the first line of your blank page, ready to go. For a larger keyboard that can help you type quicker and more accurately, flip your iPad horizontally.
Title your notes page succinctly on the first line. Only the first 20 or so letters of your title will display in a notes index that iPad automatically generates to help you find particular notes later on. So, use abbreviations and short, descriptive titles liberally. For example, enter 'OCCC Conf 6/11' or 'To-Do List.'
Tap the 'Return' key on your keyboard to begin typing your notes. If you've copied information to your iPad clipboard from another source, such as a recipe from a website, double-tap on your cursor and select 'Paste.'
Use iPad typing shortcuts and tricks to minimize keystrokes. They are especially helpful when note-taking speed is critical. For example, double-tap the spacebar to end a sentence with a period and begin the next sentence with a capital letter. For a list of other speed-typing tips, see the Resources.
Tap the 'Keyboard' key on the bottom right corner to make the on-screen keyboard disappear. This will help you review your notes more easily.
Tap anywhere within your notes to summon back your virtual keyboard. To edit your notes, tap on the line in which you'd like to place your cursor to add or revise text as needed.
