Make the calltips go away?

I unclicked the ‘auto complete’ option in preferences, since it mentions the calltips, but it did nothing… (even after restart); how to make them not appear when I type a function?

e.g. I type in the command line “np.mod” and a screen-sized window appears explaining mod() to me, occluding everything. how to make it go away?

ESC makes it disappear, ok, but how to make it never appear if that’s what i want?
