Options¶
Tools > Options… opens the settings. The pages are listed on the left, and each one has a page of its own here, in the same order.
OK applies the changes and closes the window, Apply applies them
and keeps it open, 
Cancel discards them. Hold the mouse over a setting to
see what it does. A click on a setting’s name, or on the hint beside it, works
as a click on its check box; beside a list or a field, it puts the cursor there.
