Context Menu in KDE

[Roy S Schestowitz <roy-dot-schestowitz-at-isbe-dot-man-dot-ac-dot-uk@use-address-before-at.com>]

I must admit that I miss the ability to press a keyboard button in order to
open context menus? Under Window$, there is a button adjacent to $tart, but
it is of no use here. Is there any accelarator that will do the same thing?
Maybe some ALT or CTRL option?
