Zoom Control

Click the Zoom Control or press V to activate.

The Zoom Control displays the current magnification (zoom level) that is being applied to the image that is being shown in the Preview Viewport. If you click on this control a menu will be presented which will allow you to change the current zoom value.

The menu offers a selection of numeric zoom values for you to choose from plus the following special options:

Actual Pixels sets the zoom value to 100%.
Fit In View sets the zoom value so that the largest extent of the image just fits inside the viewport. This menu selection also toggles the automatic Fit In View mode.

A check mark will appear beside the Fit In View selection when automatic Fit In View mode is enabled. When this selection is checked, the image zoom will automatically be readjusted whenever the plug-in dialog is resized so that the entire image will always just fit inside the viewport.

Selecting Fit In View, when it is already checked, will disable this automatic readjustment, leaving the image at its current size. The check mark will no longer appear and the zoom will no longer change when the plug-in dialog is resized.

Note that selecting a specific zoom value will disable the automatic Fit In View mode.
Fit On Screen resizes the dialog to fill the screen. The zoom will be changed if Fit In View mode is already enabled.

Keyboard Shortcuts

If the Zoom Control menu is displayed, the following keyboard shortcuts can be used to select a menu item:

The Up Arrow or Down Arrow keys will move the selection up or down.
The number keys will move the selection to the next menu item that begins with that number.
The letter keys will move the selection to the next menu item that begins with that letter.
The Enter key will cause the menu item that is currently selected to be initiated.

Note that if you enter a number or letter key and that key specifies a unique menu item (e.g. Only one menu item begins with 4), the chosen menu item will be initiated immediately.
