How can I mark a series of images in a list with checkboxes?

2. Please check whether the option: "<-------> Selection (arrow keys)" is active.  

3. Mark the pictures in the list view

4. Now use the left-right arrow keys

(... see Image-1 Point 1  to 5)

Left arrow key to mark the left picture / pictures with check boxes and the right for the pictures on the right 

 

PS: The first keystroke marks the second one, which de-marks the image (check box)
