All of the Takeoff Help pull-down menu selections are standard throughout other parts of Estimating Series programs. See the Help topic in the Estimating Help.
Note: If the Esti-Sketch plug-in is installed on your system, "Esti-Sketch" will be indicated in the "About Takeoff" window.
Context-Sensitive Help can be activated by using the click the 
button on the toolbar, a question mark will then be added to the cursor. Next click on the Takeoff element you wish to receive information on. The Help will then open directly to information on the selected Takeoff element. If no direct information on the selected Takeoff element is available, the Help will instead open normally.
