modifying kde's right click menu

[John]

Hi
When I right click an item in Konq or search the behaviour of "open with" 
changes sometimes it offers what I did last, for example open with kate, on 
certain things it doesn't. How can I change things so that the previous open 
withs are allways shown?
Also how can I add additional commands to the right click operations menu?
For example open with kate. That would be my preferred solution.

Regards John
PS The spell check seems to work every where it  should apart from the  
subject line of an email?
