Re: More than two softkeys
The concept of middle soft key (often referred as [b]MSK[/b]) was introduced with S60 3rd FP2, and it was triggered via pressing "Enter", so the navipad/stick. It was defined via adding a 3rd element into a standard CBA resource. And it was possible to emulate.
However what you see in Symbian^3 apps is a toolbar (AVKON_TOOLBAR resource). When combined with KAknToolbarWithoutCba flag, there is no CBA pane visible, and the toolbar is shifted to the bottom of the screen. Toolbars have been introduced with touch-enabled UI, and thus their items have no associated keycode which could be emulated. From this viewpoint they more resemble menus than CBA-s.

That is what I needed to know. Thank you kindly for the explanation!
