You can't reverse an atom or rank-0 array because it has no axes to reverse along, or it could be said no ordering to reverse.

To reverse along an axis other than the first, use Cells (˘) or Rank (⎉).

Elements are always rotated to the left, so that entry i of the result is entry 𝕨+i of the argument—or rather, entry (≠𝕩)|𝕨+i to enable elements to cycle around. This can be seen directly by using the range ↕n as an argument: then the value of 𝕩 at index i is just i.

Rotate also allows 𝕨 to be a list (or unit array) of integers, in which case they're matched with leading axes of 𝕩. This means the length of 𝕨 can't be larger than the rank of 𝕩, or there wouldn't be enough axes to match. This rule also explains why 𝕩 has to have rank one or more when 𝕨 is an atom, because 𝕨 is treated as the one-element list ⥊𝕨 in that case.

The expression below rotates the first (vertical) axis of tab by one element, and second by two. So the line of capital letters goes from being one away from the top, up to the top, and the column with '2' goes from horizontal index 2 to index 0.
