# Parameters

Every control on the node, grouped by the folder it lives in. The description column is the first line of each control's own tooltip, so the two always agree. The `Internal name` column is what you use in a channel reference or a script.

164 controls in total.

The Manual Overrides (Global) folders are the street-wide half of the Advanced rows; each row also appears on every sign's own card. See [Advanced rows](../control/advanced.md) for how Auto and Custom work. The two VEXpression hooks are documented at [VEXpression](../control/vexpression.md).

Rows inside a sign card carry a `#` in the internal name; on the node it is replaced by the card number, so the Title on card 3 is `psa_title3`.
