Most of the navigation actions available in the code viewer are also available in the IL Viewer. For more information, see View Intermediate Language (IL).
In the IL Viewer window, if IL presentation is selected, you can learn descriptions of IL instructions in tooltips when hovering the mouse over an instruction. The descriptions are taken from MSDN and from the ECMA-335 standard (Partition III: CIL Instruction Set).
