Specifies a module with its optional parameters which should be spawned. Currently several modules, including FvwmButtons, FvwmEvent, FvwmForm, FvwmGtk, FvwmPager, FvwmScript support aliases. Aliases are useful if more than one instance of the module should be spawned. Aliases may be configured separately using * syntax. To start a module FvwmForm using an alias MyForm, the following syntax may be used:

Module FvwmForm MyForm

At the current time the available modules (included with fvwm) are FvwmAnimate (produces animation effects when a window is iconified or de-iconified), FvwmAuto (an auto raise module), FvwmBacker (to change the background when you change desktops), FvwmBanner (to display a spiffy XBM, XPM, PNG or SVG), FvwmButtons (brings up a customizable tool bar), FvwmCommandS (a command server to use with shell's FvwmCommand client), FvwmConsole (to execute fvwm commands directly), FvwmCpp (to preprocess your config with cpp), FvwmDebug (to help debug fvwm), FvwmDragWell (the place to drag&drop to), FvwmEvent (trigger various actions by events), FvwmForm (to bring up dialogs), FvwmGtk (to bring up GTK menus and dialogs), FvwmIconBox (like the mwm IconBox), FvwmIconMan (a flexible icon manager), FvwmIdent (to get window info), FvwmM4 (to preprocess your config with m4), FvwmPager (a mini version of the desktop), FvwmPerl (a Perl manipulator and preprocessor), FvwmProxy (to locate and control obscured windows by using small proxy windows), FvwmRearrange (to rearrange windows), FvwmSave (saves the desktop state in .xinitrc style), FvwmSaveDesk (saves the desktop state in fvwm commands), FvwmScript (another powerful dialog toolkit), FvwmScroll (puts scrollbars on any window), FvwmTabs (a generic tabbing module), FvwmTaskBar (a Windows like task bar), FvwmTheme (managed colorsets, obsolete), FvwmWharf (an AfterStep like button bar), FvwmWindowMenu (a configurable fvwm menu listing current windows), FvwmWinList (a window list). These modules have their own man pages. There may be other modules out on there as well.

Modules can be short lived transient programs or, like FvwmButtons , can remain for the duration of the X session. Modules are terminated by the window manager prior to restarts and quits, if possible. See the introductory section on modules. The keyword Module may be omitted if modulename is distinct from all fvwm commands.
