When creating custom menus the "copy" versions of all of the main menus that filemaker provides makes it easy to modify the existing main menus. Is there any way to get copy versions (or some other solution) of the sub-menus? For example, I'd like to slightly modify the Manage sub-menu (under the file menu).

thx

No ,till fm11 version you can only edit Main menu labels.For Sub-Meny it is definitly not possible.

Sorry,I again verified it.It is possible.You have to just change sub-menu name from edit option of menu name section.

Click on any menu name from your craeted new custom menu set

like "File copy;Edit copy;.....".Just click on File copy --->click on Edit.window will open--->click any submenu for example click on "Open" submenu of "File copy" main menu---->Click check box "Item name" from section "Override default Behaviours"---->Given name "&open..." to your desired name like "&openme". do same with all submenus click ok.it will reflect into your application
