 Blue underline & insertion line enclose expressions
 Use arrow keys & spacebar to move

31

 Click in expression with mouse
 Use <space> to select more/less of expression
 Use arrow keys to move around in expression
 Insertion point is where things happen

32

 Spacebar select more & more of expression & then returns to
start

33

 What gets selected depends on where you start

34

 Arrow keys move insertion point
 Insert key swaps sides
