Query Language Reference
What is a Query?
Underlying Altium Designer is a powerful data filtering and editing system that lets you instruct the software to return you a specified set of objects. This instruction is entered in the form of a Query. 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.
For help on a specific query keyword, press F1 when the cursor is in the keyword. Use the Query Helper dialog for a list of keywords. To easily re-use popular queries add them to your Favorites (copy them from the History list). Favorites can be accessed from the Favorites dialog, or by pressing the Y shortcut in the schematic or PCB editors.
