# $ Functions

The "dollar functions" are those functions that are included (and published) in the In-Sight 3D API and allow users to programmatically invoke functions or HMI controls. With the Script Editor open, the Toolbox provides a list of $ functions and properties. These can be dragged from the Toolbox directly into the Script Editor. Alternatively, typing $ in the editor will open an intellisense window, listing all available $ functions and properties and their syntax.
