From the "show-azimuth-elevation_v1.3.celx" written by Harald Schmidt, I created a new celx file to simulate a "Stellarium like behaviour" in Celestia.
So, I changed and added in the source file :
- The keyboard input of the Longitude and Latitude values of the observer place wanted
- the Celestia:synchronous(...) (equivalent to Y)
- the Celestia:gotolonglat(...)
- the Celestia:gotosurface(...) (equivalent to Ctrl+G)
All works ok

But, I dont know how to set the arrows keys behaviour as if I was typed Ctrl+F ?

Thanks for your help
