Strange.
But, what is your actual question?
Operating a menu bar can usually be done using a combination of the Alt key, and different letters. E.G. in most applications, Alt-F should open the "File" menu. Following that with Alt-O is commonly used to open a file.
Alternatively, you may be able to use the arrow keys to navigate through a context menu, and the Enter key to choose an item within the menu.
However, this would require more keypresses, and thus more time, the further from the top or bottom menu item the target menu item is, whereas using Alt key combination should only require a single keypress action for each menu depth.
Certain menu items may also have direct keyboard shortcuts, E.G. Ctrl-S to save a file, which would not require opening the menu at all.
How you choose to structure your commands, would depend on your workflow.
If you want to be able to speak "save file", using a direct keyboard shortcut would be a good option.
If you want to be able to speak "File" to open the menu, followed by the next menu item, you may want to consider using a "Wait For Spoken Response" action rather than separate commands for menu items, as they would only be relevant after opening the menu, followed by a condition to press the relevant Alt key combination.
