It’s the top File menu item in all four Office programs, and it opens the Office Project Gallery window when selected. Keyboard shortcut: Shift-⌘-P.

Creates a new Entourage file. Since Entourage can create a variety of files, the New command has its own submenu, filled with commands that create a new Entourage document or element.

Opens the selected item into its own window, whether it’s an item in the Folder List (such as a mail folder or the Address Book) or an item inside the browser window (such as a folder or a contact). The command even tells you what you’re about to open (“Open Message” for example). Keyboard shortcut: ⌘-O.

Opens another Exchange account’s shared mail folder, calendar, or contacts list. (This command is only available if Entourage has an Exchange account configured.)

Closes the frontmost open window, even if it’s the Progress window. If Entourage’s main window is the only one open, this command closes it. Keyboard shortcut: ⌘-W.

Saves any changes made to the frontmost window, whether that window is an email message (which then gets placed in the Drafts folder) or a contact. If the document in the frontmost window hasn’t been changed, then the Save command is disabled. Keyboard shortcut: ⌘-S.

Saves the frontmost window as another file. This command essentially makes a copy of the file and closes the original, allowing you to choose a new name and location for the file.

(Available in Calendar only.) Lets you save your calendar as a Web page, so that others on the Internet can see what you’re up to—if you really want that kind of scrutiny (Saving Calendars as Web Pages).

Throws out any changes you’ve made to the file in the frontmost window since you last saved it.

Opens Entourage’s Import window, which lets you bring in information from various email, personal information manager, and text-based mail and contact files (Adding Holidays).

Saves Entourage’s contacts as a text file, which you can then use in another program, or exports items to an Entourage archive (Exporting Contacts and Archives).

Initiates the sharing of a project (Notes).

Lets you subscribe to a shared project that you or another Entourage fan created.

Opens the Page Setup dialog box, where you can control how Microsoft Office prints your pages (on which kind of paper, and so on). The options here depend on the kind of printer you have selected.

Prints a copy of the frontmost window (or the item selected in the main window) without opening the Print dialog box. Think of it as the fast track to printing. Keyboard shortcut: Option-⌘-P.

Opens the Print dialog box, where you can specify the number copies you want printed, among a multitude of other settings. Keyboard shortcut: ⌘-P.
