Two others I forgot to mention - type just "0" as an alias for the 0,0,0 origin point, and also you can prefix polar coordinates with w to get world polar coordinates, like w5<25 - that's distance 5, angle 25 away from the origin (not relative to previous point)

> Pss the "r" takes...the fonction "Rotate" (select object to Rotate)and not the next point of the line ??? :)

I think that's because you've got R=Rotate defined in your shortcut keys.

You can also use @ in place of r for relative coordinates, like @2,2 .
