[OSM-newbies] JOSM - create node at given location

[Iain Simpson]

I feel that there should be an easy way to do this, but I can't find it 
in the documentation

I have been given the location of some POIs as OS locations.
I've converted these to lat/long to add them to the map.

I can use the 'Jump to Position' option but cannot see a way to create a 
note at this point. (the position jumped to is not shown on the screen).

Associated question - How do I modify the location of a note without 
using the mouse/keyboard.
