I have no idea yet. Just found that signal and had no time to investigate

Not all of them have getter methods. All i added do not have one and the
getter methods weren't complete to start with. David said - and i agree - we
should deprecate the getter methods. They only clutter the api. At least for
StandardActions. I personally see no need for KStandardShortcut::reload()
either. KStandardShortcut::shortcut(KStandardShortcut::Reload) is just fine
The main question to answer is if standard action automatically means standard
shortcut. And if not how to determine which standard actions deserve a
So what's the purpose of Standard Actions. Easier setup? Consistent wording?
Consistent shortcuts? The latter would imply that each standard action should
have a standard shortcut associated.

I will put that on my todo list.

FullScreen is CTRL-SHIFT F if i understand that correctly. But it doesn't work
either. The other problem with the standard shortcuts is: "they have to be
used to be active" :-)
