In the XBetza notation used by the Interactive Diagram, an 'i' modifier in a continuation leg stands for 'iso', and can be used to indicate that a slider leg must be of equal length as the preceding leg. So masR would be a hook mover that turns a right corner, and can have both legs of arbitrary length. But masiR would need both legs to be of the same length, and can thus only reach squares on a diagonal through it. The Sissa would be mavsiQ, where 'vs' expands to (f+b)(l+r) = fl + bl + fr + br, i.e. turning 45-degree or 135-degree corners.
This can also be used to indicate rifle captures by sliders, as a back-and-forth move that brings the slider back exactly to its square of origin. E.g. mRcabiR for a Rifle Rook.
