How do I translate a UV set of faces keeping the vertical or horizontal axis fixed? How do I translate a UV set of faces keeping the vertical or horizontal axis fixed?
Tried with ⇧ Shift, ⎈ Ctrl, ⎇ Alt, no way: ⇧ Shift is for sharp movement, ⎈ Ctrl is for snap, both of them are not sharp enough, ⎇ Alt does nothing.
Press G for the grab command and you can constrain movement by pressing either X or Y afterward.
