Dear Rglers,

when using a callback in rgl (Windows, if it matters)

http://finzi.psych.upenn.edu/R/library/rgl/html/callbacks.html

I would like to get the Asynchronous keyboard status (as least Shift/Control, but preferably other key) to set markers in a plot.

getGraphicsEvents seems to be limited to normal graphics windows.

Dieter
