Interaction step

Press key

The press step sends a single key or a key combination to the page, for example Enter to submit a search, or a shortcut the site exposes.

In a workflow, this is a step object with "type": "press". Steps run in order, and each step can read the outputs of the steps before it. See the fullworkflows reference for the 30+ step types.

Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.

Fields

FieldTypeDescription
keyrequiredstringA key name such as Enter, Tab, ArrowDown, or a combination like 'Control+A'.

Example

A single press step as it appears in a workflow's steps array:

{
  "type": "press",
  "config": { "key": "Enter" }
}

How it behaves

  • Use Enter on a focused search field instead of hunting for a submit button.
  • Modifier combinations use + syntax, e.g. Control+Shift+K.

Where it runs

The press step executes wherever the run executes. On yourlocal or BYO agent there is no compute charge and the agent can reach intranet-only systems; on Writ cloud the run is metered by running time (~$0.12 per browser-hour, from your plan’s included usagewallet.

  • Recorder - capture steps by clicking through a site.
  • Managed endpoints - turn the workflow into a REST endpoint, or an MCP tool.
