When you install the Smode software, you are given the option of downloading the Smode documentation so that it can be easily accessed at any time directly from the software UI, even off-line.
Enter the name of the element you want information on in the Documentation panel search bar, or use the cursor research icon [F1] in the top left corner of the panel and click on the element to open its documentation.

You can also access to the full documentation, via the HELP menu.
