# Change definitions key actions actionId

Changes one action-bar button: `label` (up to 60 characters), `icon`, `config` and `enabled`. A disabled action stays on the bar and stops being offered, which is the reversible way to take a button out of use. An absent field is left alone; answers 204. Workspace admin.

Access class: `def:admin`.
