/**
 * It's allowed to assign multiple actions to the same keyboard shortcut. Actions system filters them on the current
 * context basis during processing (e.g. we can have two actions assigned to the same shortcut but one of them is
 * configured to be inapplicable in modal dialog context).
 * <p/>
 * However, there is a possible case that there is still more than one action applicable for particular keyboard shortcut
 * after filtering. The first one is executed then. Hence, actions processing order becomes very important.
 * <p/>
 * Current extension point allows to promote custom actions to use if any depending on data context
