The Settings->Zoom submenu allows you to change the magnification. You can choose one of the predefined settings or you can specify an arbitrary setting using Settings->Zoom->User Defined. The magnification value may be entered as either a percentage or a decimal value. For example, either 150% or 1.5 to zoom by a factor of 1.5. You can also change the magnification using the zoom function in the status bar. Click on the decrease button to reduce the magnification or on the increase button to increase the magnification, according to the list of preset values. Alternatively, you can double-click to open the zoom dialog box or menu-click on the percentage value to open a popup menu.
