I presume you're not using IDLWAVE? If you are, you could:
IDL> OPLOT [C-c ?]
and the HTML help would popup for OPLOT. In fact, you could try:
IDL> OPLOT, [Tab]
get a list of keywords, and right click on any of them to have the
HTML help queued up to the correct section documenting that keyword.
What else can IDLWAVE give you help on, either in the HTML help pages,
or directly in the source code of a relevant routine? Here's the
list:
Routine name The name of a routine (function, procedure, method).
Keyword Parameter A keyword parameter of a routine.
System Variable System variables like !DPI.
System Variable Tags System variables tags like !D.X_SIZE.
IDL Statement Statements like PRO, REPEAT, COMPILE_OPT, etc.
Class name A class name in an OBJ_NEW call.
Class Init Beyond the class name in an OBJ_NEW call.
Executive Command An executive command like .RUN. Mostly useful in
the shell.
Structure Tags Structure tags like state.xsize
Class Tags Class tags like self.value.
Default The routine that would be selected for routine
info display.
