The input command is used to enter text into the current element. For example:
- You may want to search for a query on a search engine. You can use a value in your scope (Input value option) to determine the text to input.
- You might first get a list of cities in California from Wikipedia, then use each entry in the list as an individual query to monitor keyword rankings.
- You may need to login to a page before accessing your data. You can first select the username box, and input it, and do the same for the password before selecting and Clicking on the login button.
The value to be entered into the current element.
There are two options for this type of input:
- Text - Treat the input value as a constant string, and enter it into the current element. You should input this in quotations, like this:
"Input goes here"
- Expression - Treat the input value as an expression, evaluate it in the current scope, and enter it into the current element.
