There are plenty of osg examples that show how to create your own event
handler by subclassing from GUIEventHandler. For example look at osgpoints.
Make your own event handler, and change the text visibility (using its node
mask) based on whatever keys you choose.
To update text dynamically, use
Use event handlers, node masks or a switch.

Hello ravidavi,
Thank you for your your answer.

If you will be dynamically changing your text, then specify that when you
first create it:
osgText::Text* text = new osgText::Text;
text->setDataVariance(osg::Object::DYNAMIC);
Note that setting the data variance is important for multithreaded Viewers
Seconded. Silver Lining will probably solve all your problems and the
licensing cost is SUPER reasonable.
If you have any questions, hit me up or Frank Kane (the author of Silver
Lining and founder of Sun Dog) is super responsive.

HI Bruce,
When I wrote the osgParticle::PrecipitationEffect is was specifically for
local ground based usage, I didn't attempt the handle the case of a
geocentric scene. Off the top of my head I don't know if would be possible
to adapt it - I'd need to sit down spend time review the code and
