With the set of Actions Helium Scraper provides, you can automate it to manipulate and extract data from the web. To get started, select the Actions 
tab at the bottom left. By default, there is an item called Actions tree 1. You can expand it by clicking on it. You will see the New Action 
button, with which you can add actions to the actions tree. The action will be added as a child node of the currently selected node if the latter can contain child nodes. Actions that can contain child nodes will execute them from top to bottom until a particular condition is met. This condition depends on the particular action that is executing its child nodes.
Actions can be skipped by selecting the Skip item in the context menu after selecting and right clicking an action. They can also be set not to show error messages if the error is ignorable (i.e. if the error has an Ignore button) by selecting the Ignore Errors item.
To see the list of actions that can be used, see the Actions List section. To see how you can create customized actions see the Execute JavaScript action and the Actions Tree Setup HTML.
