In this lesson we will learn about TextEdit. This is a simple word processor that comes built in on macOS. To open it, we can click on its icon from the dock. If you already have it there as I do. Or you can go to Finder, then Applications, then double-click on it. Or you can also open Launchpad, then go to TextEdit. Or you can open Spotlight and just type TextEdit. When it's opened we see this window, to either open an existing document or create a new one. So I'll click on New Document. Now there are two modes in TextEdit. One is the Rich Text Format, or RTF for short. Then there's the Plain Text mode. This window in front of us here is the RTF mode because it allows us to format the text, using all these features in the toolbar. For example, let me copy and paste some random text here, and I can use all these features in the toolbar to format the text accordingly. Like change the font, make it bold. Change the size, color orientation, and line spacing. So TextEdit contains many of the basic features of big word processors like Microsoft Word. I can also add an image by dragging and dropping it inside the document, or I can also add a table by going to the Format menu, then choosing Table. This will create a 2x2 table and you have this window to further control the format of your table. So that was the Rich Text Format, but you can also use TextEdit to create Plain Text documents. To do that, I go to the Format menu, and choose Make Plain Text. A warning appears that we will lose any formatting features because switching to plain text is just that, it's plain text. So I click on okay, and now all the formatting options we had before are now all gone. Also, notice that the toolbar now does not have any of the formatting features that were here a moment ago when I was working in the Rich Text mode. But we can toggle between these two modes as we wish. Then when you are ready to save the document, we go to default menu, then choose Save. From this window, I can choose where to save this file, as well as choose what file type to save it as. The default is the RTF format, but I can save it in another file format as well. Another feature about TextEdit is that you can open these documents in other word processors, like Pages or Microsoft Word, and it also works the other way around as well. For example, if someone sends you a Microsoft Word document and you don't have it installed on your computer, you can still open the actual Microsoft Word document in TextEdit, but it will be in plain text. So while you will be able to read the text the document will not contain any of the original features and formatting. And like any other app in macOS, we have some settings we can control by going to the File menu, and then Preferences. Here we can see settings like in what mode to open text editing, as well as many other settings we can control here. Please explore these options, and customize the app as you see fit. So in this lesson, we learned about the basics of using the TextEdit app. Thanks for watching.
