[GRASS-user] d.rast.edit does not save edited cells (?)

[Nikos Alexandris]

Ohhhh! I got it!

It's the "*" I am using. With the value "66" for example it worked!

But why not with "*". It's a perfect tool if one needs to manually
correct some details.

And why not having a magic "key" with which one can "fly" over pixels
with the mouse pointer and assign new values instead of "countless
clicks".

I know many occasions were this is necessary to be done and there is no
fastest and more precise method than just doing it by hand.

Cheers ;-)
