This has been a conversation that has been posted in the IxDA and SIGLIA
mailing lists many times, and it has come to this: "it depends". I am in
favor of the action button [ok] to be on the left, with the condition
that the form is a single page and the action will be carried out
I would like to see if somebody has run usability tests or research to
define best practices for this argument.
Has anyone done extensive user testing for placement of OK, CANCEL
buttons? Should OK be on left and CANCEL on right? I have seen many
theories to how it should be but didn't come across any results of an
actual user testing on this subject. If anyone has information about
this, please let me know.
