The eCos Configuration Tool contains several methods for accessing online help.

### Context-sensitive Help for Dialogs

Most dialogs displayed by the eCos Configuration Tool are supplied with context-sensitive help. You can then get help relating to any control within the current dialog box by

- pressing F1

A brief description of the function of the selected control will be displayed.

- Clicking the help (question mark) button on the dialog (Linux) or in the dialog caption bar (Windows)

A question mark cursor will be displayed. Click on any control to display a brief description of its function.

Some dialogs may have a Help button. You can press this to display a more general description of the function of the dialog box as a whole. This help will be in HTML form; for more information, see below.

### Context-sensitive Help for Other Windows

In the Help menu, click eCos Configuration Tool Help (or press F1 ). A HTML page describing the general operation of the currently active window will be displayed. This help will normally be in HTML format; for more information, see " Methods of Displaying HTML Help ".

### Context-sensitive Help for Configuration Items

In the configuration window, right-click on a configuration item. A context menu will be displayed; select Visit Documentation to display the page in the eCos documentation that most closely corresponds to the selected item.

### Methods of Displaying HTML Help

There are three ways of displaying help, configured by clicking on the Viewers tab of the Settings dialog.

1. Using the internal help system. This will show an internal viewer similar to Microsoft HTML Help, with a contents hierarchy on the left and HTML pages on the right. The index is regenerated for each repository. If the documentation in the repository has changed but the contents does not reflect this, please use the Tools Regenerate Help Index menu item.

2. Using the default HTML browser. On Unix, you will need a .mailcap entry similar to this:

   `text/html; netscape -no-about-splash %s`

3. Using the specified browser.
