Do you find yourself getting frustrated when trying to figure out how to insert certain characters (like ⌘, ⌦, §, or ¶) into documents? I know that I used to – until I learned how to use the Character Palette. Now this process is very quick and easy.
There are a couple of different ways to access the Character Palette, including (1) press Command, Option/Alt and T together to open it, and (2) go to the Edit menu and choose Special Characters From there, you simply locate your desired characters and insert them by either clicking "Insert" or dragging the character into your document.
If you find that there are certain characters that you use more frequently, you can add them to your "Favorites" by selecting the character, clicking the "gear" icon on the bottom left, and selecting "Add to Favorites". Finally, the search window in the bottom right can help you more easily locate certain characters if you need assistance.
