This sample shows how to monitor keys that are pressed when mouse events on the map. This same approach can be used with layers as well.
By default mouse events will know if the CTRL, ALT, and SHIFT keys are pressed, but won't know about other keys. This sample monitos the key down and down events to support all keys.
There are certain key down + mouse events that are native to the map as should be mainted to ensure a consistent across all implementations of Azure Maps.
For example, SHIFT + mouse down and drag that will draw out a rectangle area to zoom the map into quickly.
A full list is documented <a href="https://docs.microsoft.com/azure/azure-maps/map-accessibility" target="_blank">here</a>.
