For most tools, the Inspector Bar is divided into three parts.
On the left side are two icons, Cancel and Properties.
Cancel: Ends an operation without completing it. For some tools, once the operation is complete the tool remains active. You must click Cancel, or activate another tools, to exit the tool. The hotkey for Cancel is the Esc key. 
Properties: Opens the Properties window for the object you are creating. See Object Properties. 
The middle section of the Inspector Bar contains the numeric fields. For example, when creating a line segment in the Polyline tool, you can set the Length, Angle, and Start and End Widths. For a circle, the fields would be Radius, Diameter and Circumference. When moving the cursor to position or size an object, the values in the fields update dynamically. 
You can access the numeric fields via the cursor, or by pressing Tab or Ctrl+E. You can also press Tab to scroll forward to the next field. Return to the drawing by pressing Esc or clicking in the drawing.
...
Locking: For some fields you can lock their values by clicking the lock symbol. This means that no matter where you place the cursor, the value will remain fixed.
The right side of the Inspector Bar contains options relevant for the tool or mode.

There are two common local menu options that appear for many functions: Finish and One Step Back.
Finish: Completes the operation and exits the tool. For instance, when creating a polyline, you can click Finish after creating the last segment. The hotkey for Finish is Alt+F. 
...
Note: For many tools, double-clicking when creating the last component of an object is equivalent to clicking Finish.
...
One Step Back: For tools that require multiple steps, this enables you to scroll backward through the steps already completed until you reach the desired start point, then continue working. 
When in Select Edit mode, the Inspector Bar has a different appearance. The numeric fields enable you to change the size, scale, and rotation of the selected objects, while the local menu options include Make Copy, Selector properties, etc. Size and Position fields for 3D objects are turned off by default. See Select Edit.
