 First we have to make the machine aware of the context by adding a \textsf{sees} (\ref{seeing_a_context}) statement. To do this, place your cursor to the left of the small green arrow (\icon{rodin/structured_arrow.png}) next to your machine name \textsf{mac1}. Right click and select \textsf{Add Child $\rangle$ Event-B Sees Context Relationship}. A \textsf{SEES} heading will appear with the value \textsf{--undefined--}. Place your cursor over the undefined section and click. A small box listing all of the contexts in the project will pop up. Select \textsf{ctx1}:
