To get notified about new strings that need to be translated you can subscribe to an rss feed for your language in an RSS reader of your choice (e.g. https://www.apptranslator.org/rss?app=SumatraPDF&lang=de is rss feed for changes in German language)

& means that the following character is the hot key. For example, &File means that f key is a hot key in menu items etc. Hot keys are rendered with underline in menu items (although it can be disabled system-wide).

You don’t have to add hot keys in translations - those are for convenience and easier use with a keyboard.

In translated text a different character could be an accelerator.
