I have made some more observations around this issue I have. As you have already said, by clicking the Add Markers button, the map is losing focus and so I need to spoof another click event so the keyboard navigation re-enables. I have a setMapFocus and setBodyFocus for controlling what element is in focus on the page.
On an initial page load, with no markers added, you can use the arrow keys as expected and also hold the Ctrl key down and drag with the mouse to use the keydragzoom utility. When clicking the Add Markers button the showPoints function is being called at the end of which another is a call to the setMapFocus function to spoof a map click event. This doesn't help my problem whereby after the markers are added I can no longer use the arrow keys or the Ctrl key drag zoom feature. However I have found that I can bring back the key navigation and drag zoom functionlity on the page through the following scenarios: 1. Click off the map area, e.g. in the white space below, and click back on the map again 2. Opening an InfoWindow and then closing it using the 'x' button in the window Its this initial draw of the units that seems to be causing the trouble, because although I am using the GEvent.trigger method to try and spoof a 'click' on the map, this doesnt seem to occuring. Latest code is at http://www.dev.robparkerdnn.co.uk/ Please help!
