I will try to explain. Assume I use transformation f. then it has coordinates f^i_j. however I may have so much these transformations that I need to enumerate f itself. If I write f^i_{kj} then it is not clear the function of k. does it enumerates f or this is index. So I clearly separate indexes that serves different functionality and each group is separated by symbol \cdot. If structure of all such indexes is the same I could use macros to write as was suggested f_{k\cdot j}^{\hphantom{k\cdot}i} (it works); but I have different index structures. It may be for instance C_1{}^i_{kl}{}^{pq}_r I use such indexes when I study tower of representations or components of Gateaux derivative. And when derivative is of high order in module I need clearly separate index that enumerates function from index that enumerate independent variable.

I don't know what you intend to write, but with "k" on the baseline for "1", I see "1 (dot) kwithioverit", with the "i" belonging to "k", and nothing else. If that's what you intended to write, then your TeX formula is wrong. It would be better to then write your formula as three components that follow each other, possibly with using relstack and phantom commands to ensure correct alignment. If, however, you meant "1 (dot)" with a superscript "i" and subscript "k", then "k" should not be on the baseline for "1" at all, because it's only a subscript if it's lower than the parent's baseline. There are various ways to force "1" and "k" to share the same baseline, but what is the mathematical concept you're trying to write out?
