There are a wide variety of possible browsers to use for displaying
the online HTML help available with IDLWAVE (starting with version
5.0). Since IDL v6.2, a single cross-platform HTML help browser, the
IDL Assistant is distributed with IDL. If this help browser is

idlwave-help-use-assistant, enabled by default, controls

idlwave-help-browser-function inherits the browser configured

Though it only impacts a few symbols, you can trick Mozilla-based browsers into recognizing ‘Symbol’ by following the directions here. With this fix in place, HTML help pages look almost identical to their PDF equivalents (yet can be bookmarked, browsed as history, searched, etc.).
