I don't know better then that you have to use the arrow keys when using the ruler.
I think this is more a question for the GE forum.
Is that a Google Earth Community tab in GE Help options that leads to GE forum webpage? If so, I've already been there but as I somehow cannot manage there. I'll try again thanks.
Btw, using arrow keys is not practical at all, it makes you working too slow and I simply haven't used to do that with the arrow keys. Don't know if that is only me but I was more pleased with earlier GE versions as installing the new versions again and again brings more and more troubles.
