You can use the help tool 
in the toolbar to display detailed help on any icon, menu, or dialog box that you use in ABAQUS/CAE. When you click the help tool and then click an item in the ABAQUS/CAE window, a help window appears containing the section from the online documentation that is relevant to that item.
To display help on an item in the main window or in a dialog box:
From the right end of the toolbar, click the help tool .
Tip:
You can also select Help
On Context from the main menu bar.
The cursor changes to a question mark.
Position the cursor over the item about which you need help, and click mouse button 1.
A help window appears. The window contains the appropriate online documentation and links to associated topics.
Alternatively, you can use the [F1] key to display help on a particular item. In most cases you can gain access to context-sensitive help by using the Help menu, the help toolbar icon, or the [F1] key. However, you must use [F1] if you are seeking information about menu items or dialog boxes that do not allow access to the help tool.
To display help using the [F1] key:
Click the feature in the ABAQUS/CAE window that you want help with. If the feature is part of a menu, do not release the mouse button.
Press [F1].
A help window appears. The window contains the appropriate online documentation and links to associated topics. If you selected a menu item without releasing the mouse button, that menu disappears.
Note: ABAQUS/CAE also provides brief “tooltips” that describe the function of tools in toolboxes and in the toolbar. To see a “tooltip,” position the cursor over a tool and leave it stationary for a short time.
