To limit the display of classes, enter one or more keywords in the filter box and press ENTER. Only classes that contain all given keywords anywhere in their name or definition will be displayed. To list all available classes, clear the filter box and press ENTER.

Filtering is case insensitive and the filtering process has some limited knowledge about graph names. E.g. if you filter on 'chair', 'fork' will also be found. Use LaTeX notation for super-/subscripts e.g. K_3 for K3 or S_{1,1,2} for S1,1,2 and for intersection/union (cap/cup).
