The Options dialog box contains several different pages that you can browse by pressing ctrl + tab: 
Pivot Tables, Data Currency, Scripts, General, Viewer, Draft Viewer, Output Labels, Charts, and 
Interactive.

In this example, we are viewing the Draft Viewer page. This page allows us to set options
for Display Output Items, Page Breaks, Font, Tabular Output, and Text Output. 

When you are on the Draft Viewer page, you may activate "Display commands in log" by hitting alt+D.

To save and exit the dialog box, you can hit Tab until the OK button is selected, then hit Enter.
Alternatively, you can hit Alt+A to apply the changes you have made, then hit Esc to cancel the dialog box.
