# Using Online Help

MOLMOL has extensive online help possibilities, all available documentation is available online. There is a help page for each command, available in both text and HTML format. Most of the other documentation is in HTML format. Use the `HelpViewer` command for selecting whether you want to see the text or HTML version of the command help pages, and to configure which browser should be used for displaying HTML.

## Command Help Pages

The online help page for commands can be displayed in two different ways. The first way is to click the Help button in the argument dialog of the command. The second way is to execute the `HelpCmd` command. This puts the program into help mode (indicated by the prompt in front of the command line), so that the next command is not executed, but its help page is displayed instead. The first method is more convenient, but only works for commands that have arguments.

## Finding Commands

If you are looking for a command, but do not know its name and cannot locate it in the menu, the `HelpApropos` command can be very useful. It allows you to look for commands by a keyword, and displays a list of all commands that contain this keyword in their short description, including their location in the menu and the short description.

## Other Options

Explore the Help menu to find other useful options, like displaying this manual and tutorial, or listing available standard properties for selection. The `Register` command is also available from the Help menu, you are encouraged to register if you use MOLMOL.
