The relation functions are displayed in the lower part of the Elements pane. The list is also in the context menu of the Commands window. All relations that are not contained in the Elements pane or in the context menu can be typed manually in the Commands window.

The following is a complete list of the relations. The symbol next to the name of the relation indicates that it can be accessed through the Elements pane (choose View - Elements) or through the context menu of the Commands window. Relations: is equal Icon is equal Inserts an equal sign (=) with two placeholders. You can also directly type <?> = <?> in the Commands window. does not equal Icon does not equal The neq icon or command inserts an inequality with two placeholders. You can also type <?> neq <?> in the Commands window. identical to Icon identical to Inserts a character for the identical to (congruent) relation with two placeholders. You can also type <?> equiv <?> in the Commands window. orthogonal to Icon orthogonal to Inserts a character for an orthogonal (right angled) relation with two placeholders. You can also type <?> ortho <?> in the Commands window. divides Icon divides Inserts the divides character. You can also type <?> divides <?> in the Commands window. does not divide Icon does not divide This icon inserts the does not divide character. You can also type <?>ndivides<?> in the Commands window. less than Icon less than Inserts the less than relation. You can also type <?>lt<?> or <?> < <?> in the Commands window. greater than Icon greater than Inserts the greater than relation. You can also type <?> gt <?> or <?> > <?> in the Commands window. approximately equal to Icon approximately equal to Inserts the approximately equal relation with two placeholders. You can also type <?> approx <?> in the Commands window. parallel to Icon parallel to Inserts a parallel relation with two placeholders. You can also type <?>parallel<?> in the Commands window. less than or equal to (slanted) Icon less than or equal to (slanted) Inserts a less than or equal to relation with two placeholders. You can also type <?> leslant <?> in the Commands window. greater than or equal to (slanted) Icon greater than or equal to (slanted) Inserts the greater than or equal to relation with two placeholders. You can also type <?>geslant<?> in the Commands window. similar or equal to Icon similar or equal to Inserts the similar or equal to relation with two placeholders. You can also type <?>simeq<?> in the Commands window. proportional to Icon proportional to Inserts the proportional to relation with two placeholders. You can also type <?> prop <?> in the Commands window. less than or equal to Icon less than or equal to Inserts the less than or equal to relation with two placeholders. You can also type <?> le <?> or <?> <= <?> in the Commands window. greater than or equal to Icon greater than or equal to Inserts the greater than or equal to relation with two placeholders. You can also type <?> ge <?> or <?> >= <?> in the Commands window. similar to Icon similar to This icon inserts the similar to relation with two placeholders. You can also type <?>sim<?> in the Commands window. toward Icon toward Inserts a toward relation symbol with two placeholders. You can also type <?> toward <?> in the Commands window. double arrow pointing left Icon double arrow pointing left Inserts the logical relation arrow with double bar pointing left. You can also type dlarrow in the Commands window. double arrow pointing left and right Icon double arrow pointing left and right Inserts the logical relation arrow with double bar pointing left and right with two operators. You can also type dlrarrow in the Commands window. double arrow pointing right Icon double arrow pointing right Inserts the logical operator arrow with double bar pointing right with two placeholders. You can also type drarrow in the Commands window. precedes Icon precedes Inserts the logical operator precedes with two placeholders. You can also type prec in the Commands window. succeeds Icon succeeds Inserts the logical operator succeeds with two placeholders. You can also type succ in the Commands window. not precedes Icon not precedes Inserts the logical operator not precedes with two placeholders. You can also type nprec in the Commands window. not succeeds Icon not succeeds Inserts the logical operator not succeeds with two placeholders. You can also type nsucc in the Commands window. precedes or equal Icon precedes or equal Inserts the logical operator precedes or equal with two placeholders. You can also type preccurlyeq in the Commands window. succeeds or equal Icon succeeds or equal Inserts the logical operator succeeds or equal with two placeholders. You can also type succcurlyeq in the Commands window. precedes or equivalent Icon precedes or equivalent Inserts the logical operator precedes or equivalent with two placeholders. You can also type precsim in the Commands window. succeeds or equivalent Icon succeeds or equivalent Inserts the logical operator succeeds or equivalent with two placeholders. You can also type succsim in the Commands window. To create the much greater than relation with two placeholders, type <?> gg <?> or >> in the Commands window. Type ll or << in the Commands window to insert the much less than relation into the formula. The is defined as relation with two placeholders is inserted by typing <?>def<?>. Insert the picture by correspondence character with two placeholders by typing <?> transl <?> in the Commands window. The <?>transr<?> command inserts the original by correspondence character with two placeholders. When entering information manually in the Commands window, note that a number of operators require spaces for the correct structure. This is especially true if you are working with values instead of placeholders. For example, for the "is considerably greater" relation, type either 10 gg 1 or a gg b.
