Searching in the selected row inside a database-linked power grid, sometimes I visit a small black triangular, in other cases an I-beam. (Within the screenshot below, there's an I-beam near the row exhibiting "Results/Findings.") What are the differences between your concept of these symbols? (Exist other symbols?)

Thanks, of course.

Black triangular signifies the present row. The I-beam searching symbol means you're editing the record. If you notice an asterisk icon, this means you're placing an archive.
