# $ Functions

The "dollar functions" are those functions (and respective properties) that are included (and published) in the Cognex Designer API. Consider the dollar sign as a namespace, except that you do not have to put a point after it like in the case of the other namespaces (e.g. System.Diagnostics).

Basically, what you find in the Toolbox can be also accessed if you press $ in the Script Editor. If you attach, for example, a communications card, then the Toolbox will be populated with the relevant functions which you can now access either from there or by pressing $. Toolbox contents are dynamic, depending on where you are (e.g. in the Task Editor, or Page Editor, etc.).
