The panels, toggled by pressing F4, are available as buttons on the panel selector, by default placed on the left of Opera's screen space. You can add and remove panels of your own (see below), and choose which ones to present in the panel selector. Panel and panel selector placement can also be changed by right-clicking them.

Some of the panels are hidden by default, and will appear when you enable certain features. For example, the chat panel will only appear after you have created at least one chat account. Other panels may not be visible by default, but you can enable them using Tools > Appearance > Panels.

Bookmarks

"Bookmarks" is a list of shortcuts to Web pages you wish to return to, and the bookmark panel is where you access, add, remove, edit, and sort your bookmarks in Opera. (Note: You can also go to the Bookmark menu and choose "Manage bookmarks" there, to get a larger view for editing.) Here are some of the things you can do:

Import

You can also import your bookmarks or favorites from other browsers. To do this, go to the File menu and select Import and export, and then which program you want to import from. Note that it might be a good idea to create a folder in the Opera Bookmarks first, and put all your imported bookmarks into one folder.

Mail

This panel is hidden by default and will appear only after you have created at least one e-mail or news account.
