7. The Menus / 7.3 Functions in the View Menu

7.3.6 Zoom In

Zoom In doubles the current zoom factor of the active picture window. As a result the picture will be displayed larger. The predefined shortcut of this function is "+" on the numeric keypad (on Windows) or Command+"+" (on macOS). Whether or not the window size will be adjusted, can be set in Options/ Display, page Document (see chapter 7.10.1.26).
