A couple things:
Under "In/Decremental Steps" add "You can also hold [CTRL] and scroll the mouse wheel up or down while hovering over the field.
Not critical but "In/Decremental" seems awkward to me. While "Increment" does generally imply an increase, the phrase "Incremental change" is commonly used to mean any small change towards a goal, so if it were up to me I would re-title this "Incremental Steps", but that's just me :)
Under "Text Input" the sentence: "Press Minus while hovering over the button to negate the value." is incorrect as this only works when *not* in Text Input mode, and thus should be in a section outside of the Text Input discussion.
