Show Detail Tool:

This tool is turned on and off with the '?' button in the toolstrip. It is also turned on and off when entering and exiting Clue mode (asking for a Clue when in Solve mode). The tool opens a panel at the bottom-right of the SuDoku Solver and provides an explanation for whatever the mouse is hovering over. In this example, the mouse is hovering over the 6 in Square E6, and the panel explains that the 6 is part of a triple (shown in yellow).

Diagonal:

In this third example, the tool is looking at a Killer SuDoku and the mouse is hovering over the 2 in F8. The panel explains that it is an impossible solution due to the '1 In + 1 Out' (coloured cyan) which means that the two Squares F8 and E9 must differ by 4, since the Rows F, G, H must sum to 135.
