I've created index with makeidx package. It works. What really need is to print the first letter above every group of keys (i.e. referring to the image I want to print the red letter, that I have manually inserted).
[Tex/LaTex] package makeidx: print first letter for each group of keys

In order to use section numbers instead of page numbers it is necessary to redefine the way, the index entry is written to \jobname.idx. That is basically easy, if the package imakeidx is used.
In its manual, imakeidx the author writes, that \imki@wrindexentry should be redefined to apply for other styles. Looking into the package, there is a similar command used with \thepage as argument, so redefined it, using \thesection.
However, makeindex as external processor complains about the new format if \thesection writes its numbers as 1.1 etc., i.e. with dots. Using xindy solves this problem, by applying a new alphabet or location-class, this is done in sectionindex_xindy.xdy, as well as removing the , separator and inserting ----- instead.
Content of sectionindex_xindy.xdy
(markup-locclass-list :open " ----- " :sep "")
( define-location-class "numericsections"
("arabic-numbers" :sep "." "arabic-numbers"))
( define-location-class "numericchapteralphasections"
("arabic-numbers" :sep "." "ALPHA"))

In order to make this work for figures/tables, I just redefined the command again within wrappers for figure and table environment. You have redefine \thefigure and \thetable explicitly, since it seems, that they introduce a trailing \relax command just before the figure/table number.
Please note, that this does not work correctly with hyperlinks so far,regarding the figure/table index entries.
Enabling --shell-escape is mandatory.

According to How to create capital letter for index you would require the following in a file
test.ist(ortest.mst*):Then when you run
makeindex, you need to use the-soption to specify this style file (assuming your document is calledtest.tex):The first flag set allows for the creation of the header (a letter). The second
prefixand thirdsuffixflag wraps the header contents to obtain the appropriate formatting ({\textsf{\color{red}...}in this case).* According to
makeindexman page, "If exactly one input file was given and no explicit style file was specified using-s,makeindexuses a file with the extension.mstas default style file (when present)."
