The purpose of page4 commands is to show how sorting and priority is 
handled.  
 
Commands appearing in the same menu will be sorted first by type,  
then by priority. To check how sorting accoring type is done see page3 
commands. A developer must explicitly set the type of a command but can 
omit the priority. In that case commands will be sorted in the order  
they were added, as default priority is 0. Priority can be set to a  
positive or negative integer value, a negative value is sorted before a 
positive like this: {-10, -3, 0, 5, 10}. 
 
It's also possible to sort on alphabetically on its Text() member 
instead of on its Priority() member.
