Jos,

don't expect (simulated) intelligent behaviour from the help browser.
In the help browser enter Plot into the field right to the "Go To" button
and press enter or click onto the "Go To" button (or mark the word "Plot" in
your notebook and press the help key (F1 under Windoze)). You'll get a help
page which states (among other things):

Plot evaluates its arguments in a non-standard way (see Section A.4.2). You
should use Evaluate to evaluate the function to be plotted if this can
safely be done before specific numerical values are supplied.
