The top navigation pane is created by project-specific file ohtop.htm. The modifiable information in this file is mostly “branding” information, which might be more company-specific or product-specific than project-specific. This HTML code is specified by two settings in .ohx, one for the top left and the other for the top right. Sample file OmniHelp.ohx contains “OmniHelp Example” for the left, and the W3C HTML compliance icon for the right. Both occupy individual table cells, and can be replaced by more suitable content by Help authors. When a Help author uses Mif2Go to generate OmniHelp, the changes would be made in configuration file mif2htm.ini, and passed on to the .ohx file.
The rest of the top navigation pane contains sets of buttons. The sample files include all buttons currently supported by OmniHelp code; all are removable. Settings file .ohx, and Mif2Go template file ohtpl.ini, contain variables useBackForward and useHideShow, to determine whether Back/Fwd and Hide/Show buttons are displayed.
