Initiate Edit Mode - continued
SharePoint automatically checks the page out to you when you initiate Edit Mode. Also, a yellow Status bar appears under the ribbon noting that the page is checked out and editable.
Exception
If the page is already checked-out to another user, the page will not go into Edit Mode, and will not be checked out to you. To avoid conflicts with multiple people working on the same page, only one user can edit a page at a time. The yellow Status bar will note that the page is already checked out, and will show the name of the user who is currently editing the page.
You’ll notice Edit Mode looks different than the published view of the page. There are boxes for editing, zones for web parts, gray boxes for titles, etcetera. All the changes you make to your web pages will happen in this Edit Mode.
You’ll also notice that a new tab opened in the ribbon, the Editing Tools tab, which holds both a Format Text and Insert tab. These new tabs hold the tools and commands you’ll need to work with text, and insert objects in to your page.
