Underlying Altium Designer's schematic and PCB editors is a powerful query engine. By entering queries into this engine, you can logically scope precisely those objects you require.
A query is a string you enter using specific keywords and syntax, which will return the targeted objects. There are many keywords available, allowing you to target objects by their type, their properties, or both.
The reference pages listed below detail the query language keywords available in schematic and schematic library documents in Altium Designer.
