Workbench

The workbench is the area in which the images are edited. If an image is not fully visible, for instance because it is magnified, it can be moved using the scroll bar or by moving the mouse while keeping the left mouse button pressed. The right mouse button opens the context menu. This provides an alternative way of accessing all the image editing functions which you can also find in the menus and toolbars. By double clicking the left mouse button you can display the image in full screen view. You can transfer the image to other applications using drag&drop while keeping the [Ctrl] key pressed. Similarly, you can load images from other applications into PhotoPerfect. If you wish to compare the edited image with the original during your work, you can display the original image using the [O] key. You can compare the current image with the result of the previous editing step using the key combination [Shift] + [O]. With the combination [Ctrl] + [F12] you can toggle the monitor profile  stored in the settings on and off.
