# VASSAL Reference Manual Home > Editor
## General VASSAL's Module Editor can be used to create new modules, modify existing ones, and add extensions to them. When you open a module for Edit (or select the "New Module" option), you will be presented with a Configuration Window showing the module's Components. The Configuration Window is used to edit either a Module or a Module Extension. The menu bar of the Configuration Window offers the following actions: File: Save the module or save it to a different file. Help: This reference manual. Updaters: Create a Module updater or update saved games Translate: Help translate VASSAL into another language ### Editing Modules

Right-click on any Component to get a context menu with options for that Component. Use the Cut, Copy, Paste, and Move commands to move Components around within the module, and use the Search command from the Edit menu if you need to find one. #### Properties Brings up a dialog in which you specify the options for that components. Double-clicking on a component also brings up its Properties dialog. #### Search This option from the Edit menu lets you search for Components by name or by class name (the class name pf a Component is the "type" of Component it is, enclosed in square braces in the Editor's Configuration Window, such as a "Map Window"). #### Delete Deletes the component from the module. #### Clone Makes an exact copy of the component and inserts it after the existing component. #### Help Brings up the corresponding page in this manual. #### Add ...
