This command controls the cursor during the execution of certain commands. Option can be DynamicMenu, ModuleSynchronous, Read, Wait or *. An option must be followed by a boolean argument bool. You can use commas to separate individual options. If you set an option to "True", then when the corresponding command is run, fvwm displays the cursor of the WAIT context of the CursorStyle command. "False" forces to not display the cursor. The default is:

BusyCursor DynamicMenu False, ModuleSynchronous False, \
  Read False, Wait False

The * option refers to all available options.

The Read option controls the PipeRead command.

The DynamicMenu option affects the DynamicPopupAction and MissingSubmenuFunction options of the AddToMenu command. If this option is set to "False", then the busy cursor is not displayed during a dynamic menu command even if this command is a Read or PipeRead command and the Read option is set to "True".

The ModuleSynchronous option affects the ModuleSynchronous command. If this option is set to "False", then the busy cursor is not displayed while fvwm waits for a module started by ModuleSynchronous to complete its startup.

The Wait option affects only the root cursor. During a wait pause the root cursor is replaced by the busy cursor and fvwm is still fully functional (you can escape from the pause, see the EscapeFunc command). If you want to use this option and if you do not use the default root cursor, you must set your root cursor with the CursorStyle command.
