To the far left is the Preview window, and next to that is the Source window. On the far right is the Bin window where all of the files are stored. User Buttons can be anywhere depending on the software. Sometimes in other windows, or their own windows. The Timeline Window is where most actual editing is performed. Notice that the Timeline itself is inside its own window.
The Zoom Control may be on top or elsewhere. It will often have a scroll, in/out buttons, edit-frame step and others. The Tabs are for choosing loaded projects. Usually there are User Buttons, but special features may have buttons of their own. Note the Timeline Indicator bar and the Time Display. Each Trackhas basic functions, maybe more.
The Safe Title area is useful for positioning titles. There is usually a Scroll for moving to different parts of the clip. Sometimes you may have a Shuttle for more precise scrolling. Note the begin & end Time Displays, and the usual Playback Controls. The Mark-In and Mark-Out buttons are located somewhere in the window.
