Title - Enter a title for your post. After you enter a title, you’ll see the permalink below, which you can edit.

Post editor - Enter the text for your post. There are two modes of editing: Visual and Text. Choose the mode by clicking on the appropriate tab. Visual mode gives you a WYSIWYG editor. Click the last icon in the row to get a second row of controls. The Text mode allows you to enter HTML along with your post text. Line breaks will be converted to paragraphs automatically. You can insert media files by clicking the icons above the post editor and following the directions. You can go to the distraction-free writing screen via the Fullscreen icon in Visual mode (second to last in the top row) or the Fullscreen button in Text mode (last in the row). Once there, you can make buttons visible by hovering over the top area. Exit Fullscreen back to the regular post editor.

You can upload and insert media (images, audio, documents, etc.) by clicking the Add Media button. You can select from the images and files already uploaded to the Media Library, or upload new media to add to your page or post. To create an image gallery, select the images to add and click the “Create a new gallery” button.

You can also embed media from many popular websites including Twitter, YouTube, Flickr and others by pasting the media URL on its own line into the content of your post/page. Please refer to the Codex to learn more about embeds.

Several boxes on this screen contain settings for how your content will be published, including:

• Publish - You can set the terms of publishing your post in the Publish box. For Status, Visibility, and Publish (immediately), click on the Edit link to reveal more options. Visibility includes options for password-protecting a post or making it stay at the top of your blog indefinitely (sticky). Publish (immediately) allows you to set a future or past date and time, so you can schedule a post to be published in the future or backdate a post.
• Format - Post Formats designate how your theme will display a specific post. For example, you could have a standard blog post with a title and paragraphs, or a short aside that omits the title and contains a short text blurb. Please refer to the Codex for descriptions of each post format. Your theme could enable all or some of 10 possible formats.
• Featured Image - This allows you to associate an image with your post without inserting it. This is usually useful only if your theme makes use of the featured image as a post thumbnail on the home page, a custom header, etc.

Send Trackbacks - Trackbacks are a way to notify legacy blog systems that you’ve linked to them. Enter the URL(s) you want to send trackbacks. If you link to other WordPress sites they’ll be notified automatically using pingbacks, and this field is unnecessary.

Discussion - You can turn comments and pings on or off, and if there are comments on the post, you can see them here and moderate them.
