no way to find / show all menu accelerator translations

In various packages, there are messages using the underscore character ( _ ). The underscore indicates that the character next to the underscore will be underlined in the application menu, and that the option indicated by that message can be enabled by pressing the Alt key + the underlined letter.

When translating, it is possible to translate a package's messages so that the same underlined character is displayed twice or even more in the same menu application.
In Greek for example, it is possible to have the messages "_Print" and "_Edit" translated as "_Εκτύπωση" and "_Επεξεργασία" respectively, something that can create a conflict between the two translated messages.

This is due to the collaborative nature of the translations in Launchpad, especially when translating packages containing a vast number of messages, where the collaboration of multiple translators is needed.

The Launchpad's search tool cannot be used for searching those messages as search for one character is not possible and search wildcards are not supported.

A great convenience for the Ubuntu translators, would be the addition of a filtering option that would be used to show all the messages containing the underscore character.
That way, a translator would have the ability to isolate those messages and organize the translated messages so that all key bindings in an application menu work without conflicts.

Please consider providing that option to the Ubuntu translators, so that they can in turn provide a better Ubuntu user experience when Ubuntu will be used in the user's native language.
