To start slide show in the Zoomer, it is sufficient to press Ctrl+<arrow key> ("Right" and "Down" start slide show in a forward direction while "Left" and "Up" keys - in a backward direction). Also, it is possible to select a menu item "Slide show start" from the view area menu. When the slide show is started, also a single view mode is selected. Though any keyboard key stops the slide show all mouse actions do not. So it is possible after starting the slide show to use the mouse to go from or to the single view (double click in a view area) as usual, select popup menus, press on the toolbar et so on.
Slide show rate depends on a time between two last jumps between images made with arrow keys. Or, if there were no arrow keys pressed still last slide show (or from the start of the Zoomer), slide show speed is not changed. Initial time between image switching is 1 second.
To change slide show speed, it is possible to use popup menu in a view area or to use mouse wheel rolls. Rolling mouse wheel up slows rate twice and rolling down speeds up rate of the slide show twice. Also using popup menu it is possible to change slide show direction from forward to backward and from backward to forward.
