The Help Viewer is a built-in HTML browser. ChimeraX help pages are written in HTML and can be shown in this built-in browser using the Help menu, the help command, context menus, and by clicking links from previous commands echoed to the Log. The Help Viewer starts up as a separate window, but can be managed like other ChimeraX panels. It includes a search field and icon buttons for navigation (back, forward, reload), opening a new tab, and adjusting the font size.
An important advantage of the built-in browser is that it provides a simple mechanism to execute ChimeraX commands by clicking special links, for example:
– encoded as –
<a href="cxcmd:open 1gcn">open 1gcn</a>
** The execution links will only work when the HTML page is shown in the ChimeraX browser, not other web browsers.**
Web content and HTML files in general (with or without the special command-execution links) can be shown in the ChimeraX browser with commands:
– or –
Local files can also be opened with File... Open in the menu.
