Final answer:
Global actions in Salesforce can be found in the 'Global Actions' menu in the header, inside the 'Salesforce App Launcher', and through specific components on a record page. Administrators can also manage these from the Setup area.
Step-by-step explanation:
To find global actions in Salesforce, you can typically locate them in a few different areas depending on the context in which you need to use them. Firstly, global actions can be accessed from the 'Global Actions' menu in the Salesforce header, which is available from any page within your Salesforce instance. If you're utilizing Salesforce Lightning Experience, global actions are also located in the 'Salesforce App Launcher', as well as within specific components on a record page that have been tailored to show global actions, like the 'Global Actions' component. These actions are part of the Salesforce user interface and enable users to quickly create records or perform tasks from anywhere within the platform.
Administrators can customize which global actions are available to users by navigating to the 'Setup' area, then searching for and selecting 'Global Actions' within the 'Quick Find' box. From there, they can add or modify the global actions according to the organization's requirements.
