idlwave: Help with Source

 
 4.3.2 Help with Source
 ----------------------
 
 For routines which are not documented in an HTML manual (for example
 personal or library routines), the source code itself is used as help
 text.  If the requested information can be found in a (more or less)
 standard DocLib file header, IDLWAVE shows the header (scrolling down to
 a keyword, if appropriate).  Otherwise the routine definition statement
 (‘pro’/‘function’) is shown.  The doclib header sections which are
 searched for include ‘NAME’ and ‘KEYWORDS’.  Localization support can be
 added by customizing the ‘idlwave-help-doclib-name’ and
 ‘idlwave-help-doclib-keyword’ variables.
 
    Help is also available for class structure tags (‘self.TAG’), and
 generic structure tags, if structure tag completion is enabled (
 Structure Tag Completion).  This is implemented by visiting the tag
 within the class or structure definition source itself.  Help is not
 available on built-in system class tags.
 
    The help window is normally displayed in the same frame, but can be
 popped-up in a separate frame.  The following commands can be used to
 navigate inside the help system for source files:
 
 ‘<SPACE>’   Scroll forward one page.
 ‘<RET>’     Scroll forward one line.
 ‘<DEL>’     Scroll back one page.
 ‘h’         Jump to DocLib Header of the routine whose source is
             displayed as help.
 ‘H’         Jump to the first DocLib Header in the file.
 ‘.’ (Dot)   Jump back and forth between the routine definition (the
             ‘pro’/‘function’ statement) and the description of the help
             item in the DocLib header.
 ‘F’         Fontify the buffer like source code.  See the variable
             ‘idlwave-help-fontify-source-code’.
 ‘q’         Kill the help window.
