In this case I suspect it's そろえ but I'm not pushing it.
Noun glosses please. Not [comp] really.

Spreading comments everywhere... but re: [comp] vs [print], these terms are commonly used in CSS and general web layout, things that will never ever be physically printed. So, they are valid in both camps.

See general comments on センター揃え, and voicing comments on 位置揃え. 
Reordering glosses only for consistency.  As long as whatever they are is consistent across the 10 different alignment terms, it's fine by me... ("left aligned" would also be good, or "left justified")

Uhhh... and then there's this:

右寄せ	26934	76.1%
右揃え	8449	23.9%

I'm not going to touch any of the 寄せ equivalents right now. But not sure why 揃え should be [fld=comp][fld=print], and the よせ terms shouldn't.
