string keyword

n

(where n is an integer) Move to position n in the current horizontal run (starting at zero).

Down

Cursor down (May move between math containers)

Up

Cursor up (May move between math containers)

Left

Cursor left

Right

Cursor right

End

Move to the very end of the expression

Home

Move to the very start of the expression

ENDPOS

Move to the end of current horizontal run. This is not necessarily the end of the expression. With the cursor on the + in (a+b)/(c-d), ENDPOS would move to after the b

POSLEFT

decrement position in current horizontal run. Does not obey traversal rules like Left would. Stays in current horizontal run.

POSRIGHT

increment position in current horizontal run. Does not obey traversal rules like Right would. Stays in current horizontal run.

FOCUSUP

Go up one level of nesting. E.g. from inside a sqrt sign to the surrounding expression or from the denominator of a fraction to the surrounding expression. New cursor position within the outer expression is undefined, so this should be followed by POS or similar

ID:id

Find first occurrence of id in current horizontal run, starting from the left. Position cursor before that occurrence. An id is specified as an id on the MathML tag, on input. I.e. <math><mfrac><mn id=numerator>1</mn><mi>x</mi></mfrac></math>

IDEND:id

Find first occurrence of id in current horizontal run, starting from the right. Position cursor behind that occurrence
