You are not able to create a new, empty action group. Instead, you must create or edit an existing action and then use controls on the action-configuration page to create the new group, thereby adding the selected action to that group at the same time. To do this:
1. Go to the Search Result Action page for the site level and tab for which you want to create the new action group as described in “The Search Result Actions Page”.
2. Create a new action using the toolbar or edit an existing action using the actions menu, also as described in “The Search Result Actions Page”. You should now be on the Edit/Add/Overwrite Search Result Action page.
3. Click on the New Group link in the Action Group section to open a pop-up dialog for defining the new group.
Make the following settings:
ID: Enter an ID code for the group. This is only used internally. It must be unique among all action groups and must not include any spaces. Note that if you enter the ID of a group that is already defined further down in the site hierarchy, then that group will be promoted to the current level and marked as inherited at its original level.
Name: Enter a name for the group as it should be presented on the Search Result Actions page.
Description: Enter a short description for the group. This will help remind yourself and other administrators about the intended purpose of the group.
4. Click on OK to close the new-group window. The new group is now created an your selected action has become a member of that group.
