When using the WPObject setup string MENUITEMSELECTED, the following menu IDs might be useful to you. Please keep in mind that not all of these are intended for all kinds of objects; for example, "Format disk" does not make sense on folders, and I don't know what will happen if you try this out. If you're lucky, nothing happens.

Note that the new menu items introduced by XFolder have no fixed menu IDs, so they're not listed here. The XFolder menu items have variable menu IDs, whose base is specified with the "XFolder menu item ID offset" global setting. This base is added to WPMENUID_USER, which is 0x6500 (25856 decimal), and the XFolder menu ID's are then added to that base to allow compatibility with other WPS enhancers. So if you wish to use an XFolder menu item with MENUITEMSELECTED, you need some utility such as XRAY to figure out the "real" menu id. The ID will of course change again if you change the offset setting.

The following WPS menu IDs are taken from the Warp 3 Toolkit docs (I have excluded those which make no sense when called from REXX):

  ("View" -> "Icon view", as opposed to "Open"; Warp 4 only)
WPMENUID_VIEW_TREE 0x2CD

  ("View" -> "Details view", as opposed to "Open"; Warp 4 only)
