## Move image
Switching between user interface modes.
1. Use arrows below to move to the next/previous frame.
Use the scroll bar slider to scroll through frames.
Almost every button has a shortcut.
To get a hint about a shortcut, just move your mouse pointer over an UI element.
1. To navigate the image, use the button on the controls sidebar.
Another way an image can be moved/shifted is by holding the left mouse button inside
an area without annotated objects.
If the `Mouse Wheel` is pressed, then all annotated objects are ignored. Otherwise the
a highlighted bounding box will be moved instead of the image itself.
1. You can use the button on the sidebar controls to zoom on a region of interest.
Use the button `Fit the image` to fit the image in the workspace.
You can also use the mouse wheel to scale the image
(the image will be zoomed relatively to your current cursor position).
