Associate your IDEA project with Perforce ("p4") through the built-in version control.
Once you install the plugin, you can associate a project directory with Perforce in the project settings (File - Settings..., then navigate to the Version Control panel). Make sure to edit the Perforce configuration to set the proper server connection settings.
The plugin will keep Your client's open changelists synchronized with the IDEA backed changelists, viewable under the "Changes" view. If the changelists become out of sync, you can force the plugin to re-examine the mappings by pressing the refresh button in the changes view.
Modifying a file, moving a file, copying a file, refactoring a file, and deleting a file will perform the correct Perforce operations, and put the changes into the currently selected IDEA changelist. Per-file history allows for comparing against the depot versions, even against the inherited file history.
