How i can move a face to it's facing direction?


I have got the face that you can see adobe.
I don’t want to move it at the x or y position.
I want to move it to the direction it face.
So, how i can move a face to it’s facing direction?
Thanks!

Change Transformation orientation from Global to Normal.

Thanks Burnin
I will try that!

Edit: I tried that and it worked.

Thanks!

Let’s not forget:
G and then Z,X,Y still moves to global coordinates.
However,
G and then ZZ, YY, XX, it will move accordingly to the selected orientation
