@Massimo V For the `Board` word I'd need to better know the context to translate it properly. It can have many different meanings and the one I used might be not the best translation.
`Items` is also a bit ambiguous.
The `Adding` and `Deleting` strings I supposed they are shown during this action is being worked.
Thank you Massimo!
I'm seeing that context matters! Well, all these phrases will be used under the "Edit > Undo" menu item to display the last action done. So, when there is not a undoable action left then it simply display the "Undo" word (disabled), and if the last action done is a page change then it will display "Undo Page Change".
About the "Board" word, this is the base control used in the component for adding a series of items (controls). So I think that the more appropriate meaning for the "Board" word is "a thin, flat, rectangular piece of wood or other stiff material used for various purposes".
I really appreciate the help of you all!
