SwixML, Accelerator code for delete button

Hello!

I want to invoke one of my menu items via the "Delete" button on the
keyboard.

Using this menu item definition

<menuitem id ="delete" text="Delete" Action="deleteAction"
accelerator="delete"/>

does not work, the accelerator button is not shown in the menu.

Is it possible to call menu items by pressing the delete button?

If so, what text must be written in the accelerator part of the menu
item definition?

TIA
