There are two ways of exiting presentation mode, you can press either ESC key or click with the quit button that appears when placing the mouse in the top-right corner. Of course you can cycle windows (Alt+TAB by default)
Jo kinne de presintaasjemodus op twa manieren ferlitte. Druk op de toets Esc of klik op de knop Ofslute dy' t ferskynt as jo de mûs yn de rjochter boppehoeke sette. Jo kinne fansels ek troch de finsters blêdzje (standert middels Alt+Tab).
