"An action, which can be assigned to standard shortcut" - I mean an action, which can be found in the list in:
System Settings > Shortcuts and Gestures > Standard Keyboard Shortcuts.
E.g. (such actions): About Application, Copy, Cut, Paste, Undo, Redo and so on.
Q: Is possible to invoke a standard keyboard shortcut (or an attached action) via D-Bus command? If it is possible, how to do this?
It is possible to invoke a global keyboard shortcut.
E.g., the following command invokes a global shortcut "Maximize Window" of KWin component:
(replace all the "_" with ".")
qdbus org_kde_kglobalaccel /component/kwin org_kde_kglobalaccel_Component_invokeShortcut "Window Maximize"
