142 Online help works only for system routines which are described in the

145 The function must accept four arguments: NAME, TYPE, CLASS, KEYWORD.
146 The Help buffer is current when this function is called, and the help
147 text should be loaded into this buffer. If help is found, the
148 function should return the buffer position which should be used as
149 `window-start' in the help window. Also, the variable
150 `idlwave-help-mode-line-indicator' should be set to a useful string,
151 which will be displayed in the mode line of the help window. If

153 positive integer. IDLWAVE will ensure that the help frame is at least
154 that many columns wide. Failure to find help should be indicated by
157 When this variable is non-nil, IDLWAVE will allow the mouse-3 help click
158 for every routine and keyword, even though the item may not be highlighted
159 in blue (indicating the availability of system documentation).
161 The default value for this function is `idlwave-help-with-source' which
162 loads the routine source file into the help buffer. If you try to write
163 a different function which accesses a special help file or so, it is
