Apex Editor

To edit an Apex class or trigger:
  1. In the Package Explorer, expand the project node.
  2. Apex classes and triggers are in separate folders. Expand the /classes or /triggers folder and double-click the name of the item you want to edit.
  3. Use the Source tab of the editor for writing Apex and the Metadata tab for editing the associated metadata file.

The editor has content assistance for all built-in types, including both Apex and XML metadata.
