Frame scaling is performed by the mouse scroller when the cursor is active on the image or with the buttons combination Shift+Win+Left click. To return the frame to its original scale, use the [Esc] button on the keyboard.

The accuracy of marker point location can be improved by brightening the image, switching the arrow to the crosshairs, overlaying the grid on the image, and smoothing pixels when zooming in.

The settings set on the toolbar in the Editor are saved when proceeding to the next file
