Is it possible to type in XYZ coordinate in Blender?
Yep. Select the object or vertex (if in edit Mode), then press N and enter the coordinates.
if you want to type directly a value in a slider, left click on it while holding shift.
No… as far as I know you can’t…
except, usually you can press either X, Y, Z, to just rotate in one direction… I guess that it will work for moving as well
