2) left click in box 1

3) paste (cntrl V - or right click) (it accepts a cr delimited list use "do list" button to convert OSGRs to LatLongs)

4) move cursor away from box 1

5) copy or click to your heart's content.

6) But don't try to copy from box 1 (or re-edit) - it will clear the box, that's its purpose for speed! .. (edit, copy & paste from boxes3+)

7) clicking 2osgr converts 2 numbers (comma delimited) in the LatLong box to an osgr. format eg "54.082341,-1.3973814" - You can paste or edit there.

8) NI & Ireland and Chanel Islands now recognised (Streetmap not fully covering Ireland) - LatLong to GR (& reverse conversion)

9) leading and trailing spaces and non-printing characters (eg line feeds) are ignored (mostly!)

10) "router" is a dog-leg mileage measurement list. Enter/convert each point in sequence along a route then click "router" each time. Pick points at significant bends.

11) "router" offers the area enclosed by the list (automatically closing the last & first "bends" notionally - so you don't have to). Search "Shoelace formula" for accuracy.

12) the "router" list can be used as short-term memory of unconnected points. The "bends", when clicked, load the short LatLong as a conversion.

13) KYP needs the correct county for display of green dots that pop-up interesting images of that location. Try several if close to borders!
