Note that the pan and zoom operations can be accomplished by using the mouse: left click and drag to perform a pan operation, and use the mouse wheel to zoom in and out. You can also hold down the shift key and drag over an area to zoom to that area (when the mouse button is released).
The layer value hover tool is discussed in the Layers (Add to Map) section.
Current map scale and current mouse pointer latitude and longitude is shown on the lower right of the map. Both are dynamic and reflecting the current mouse position, zoom and map location.
Note that the icon beneath the slider bar marked marked previously as the Layer Hover Tool has been replaced by a Panoramio (image) icon and function. Clicking on this will display a subset of all available images within the map extent. The link above provides details of use.
