If the cursor is on a function when Help | Function Lookup is selected (or when <Ctrl+H> is pressed)
then the Library Function Lookup dialog is skipped and the Function Description window appears
directly.
If you click the Edit button, the Function Description window will close and the library that contains
the function that was in the window will open in an editor window. The cursor will be placed at the
function description of interest.
Clicking on the Browse button will open the Library Function Lookup window to allow you to search
for a new function description. Multiple Function Description windows may be open at the same time.
