Floors and ceilings
"Auto Align Textures" actions work on floors and ceilings. It works like so:
- a linedef closest to 3d-cursor position is picked from highlighted sector.
- linedef's start or end vertex is chosen based on distance to 3d-cursor as a start point for texture offsets.
- all selected floors/ceilings are aligned to that linedef if their texture match one of hilighted floor/ceiling.
- vertical and horizontal texture scale is copied from highlighted floor/ceiling to selected floors/ceilings.

You can also align floors and ceilings to selected linedefs in Linedefs mode using "Align Ceiling Texture to Back Side", "Align Ceiling Texture to Front Side", "Align Floor Texture to Back Side" and "Align Floor Texture to Front Side" actions, available in Linedefs -> Align Textures menu.
Slopes
"Auto Align Textures" actions work on slopes. Textures are aligned to the line with "Plane align (slope)" action (181).
