The relation functions are displayed in the lower part of the Elements window. The list is also in the context menu of the Commands window. All relations that are not contained in the Elements window 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 window (choose View - Elements) or through the context menu of the Commands window. Relations: Icon is equal Inserts an equal sign (=) with two placeholders. You can also directly type <?> = <?> in the Commands window.
Icon does not equal The neq icon or command inserts an inequality with two placeholders. You can also type <?> neq <?> in the Commands window.
Icon identical to Inserts a character for the identical to (congruent) relation with two placeholders. You can also type <?> equiv <?> in the Commands window.
Icon orthogonal to Inserts a character for an orthogonal (right angled) relation with two placeholders. You can also type <?> ortho <?> in the Commands window.
Icon divides Inserts the divides character. You can also type <?> divides <?> in the Commands window.
Icon does not divide This icon inserts the does not divide character. You can also type <?>ndivides<?> in the Commands window.
Icon less than Inserts the less than relation. You can also type <?>lt<?> or <?> < <?> in the Commands window.
Icon greater than Inserts the greater than relation. You can also type <?> gt <?> or <?> > <?> in the Commands window.
Icon approximately equal to Inserts the approximately equal relation with two placeholders. You can also type <?> approx <?> in the Commands window.
Icon parallel to Inserts a parallel relation with two placeholders. You can also type <?>parallel<?> in the Commands window.
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.
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.
Icon similar or equal to Inserts the similar or equal to relation with two placeholders. You can also type <?>simeq<?> in the Commands window.
Icon proportional to Inserts the proportional to relation with two placeholders. You can also type <?> prop <?> in the Commands window.
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.
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.
Icon similar to This icon inserts the similar to relation with two placeholders. You can also type <?>sim<?> in the Commands window.
Icon toward Inserts a toward relation symbol with two placeholders. You can also type <?> toward <?> in the Commands window.
Icon double arrow pointing left Inserts the logical relation arrow with double bar pointing left. You can also type dlarrow in the Commands window.
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.
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.
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.
