By clicking the question mark symbol in the main menu and in pop-up windows you reach the online help for portatour®. It has the same content as the manual (see About portatour®) and opens in a separate browser page. This enables you to switch between the help and the program at any time.
The help is context sensitive, i.e. the displayed help content refers exactly to the program page you are currently using. Sometimes you will see links on the bottom of the help page which allow you to switch to subchapters and more detailed information. Clicking the portatour® logo in the left upper corner leads you back to the table of contents.
