runmenu: Runs Windows Explorer context menu commands on files and folders.

runmenu [/list | /exec:cmd | /verb:name | /show | /showfiles]
        [/wait: [process | thread | window]]
        [/keys: [ctrl | shift]]
        [/ext] [/nogui]
        [/all] [/justfiles] [/justfolders]
        [/verbose] file and/or folder names

runmenu [/? | /version]

   /list        Lists the context menu items available for all the objects
                you passed to runmenu. Use /list to determine the commands
                and verbs you can use with /exec and /verb.
   /exec:       Executes the context menu item indicated by "cmd".
      cmd       Names a command as it appears on the context menu. Menu
                "paths" involving submenus use the backslash as the
                separator.
   /verb:       Executes the verb indicated by "name".
      name      Names a verb corresponding to a context menu item. Not all
                menu items define verbs.
   /show        Shows the context menu and allows you to choose from it
                as if you had opened it in Windows Explorer.
   /showfiles   Prints the names of files and folders that would have been
                operated on had the command been run.
   /wait:       Causes runmenu to wait until the condition indicated by its
                argument is satisfied. You can combine multiple conditions
                in one /wait option by joining them with the + sign,
                except that "thread' and "window" cannot be combined.
                You can also use multiple /wait options subject to this
                restriction.
       process  Waits for processes launched by the context menu
                handler to exit.
       thread   Waits for threads started by the context menu handler
                to exit. Use with caution, because some handlers create
                threads that never exit. The "window" option is often
                the more suitable choice.
       window   Waits for windows created by the context menu handler
                to close.
   /keys:       Causes the context menu command to think the indicated keys
                were pressed. This can be used to modify the behavior of
                certain commands like "Delete", which normally deletes to
                the recycle bin but permanently deletes if Shift is pressed.
                You can combine multiple keys in one /keys option by
                separating them with the + sign.
       ctrl     Simulates pressing of the Ctrl key.
       shift    Simulates pressing of the Shift key.
   /ext         Includes the "extended verbs" on the context menu. In
                Windows Explorer, they appear when you hold down Shift
                as you right-click a file or folder.
   /nogui       Prevents some context menu commands from displaying interface
                elements like error boxes.
   /all         Causes wildcard expansion to find Hidden and System
                files and folders.
   /justfiles   Causes wildcard expansion to find files only.
   /justfolders Causes wildcard expansion to find folders only.
   /verbose     Prints a log of interesting events.
   /version     Prints the program version and copyright information.
   /?           Prints this usage information.

You must use exactly one of /list, /exec, /verb, /show, /showfiles,
/?, and /version.

If the usage info doesn't fit in the window, scroll back or try:
   runmenu /? | more
