Finally I've used below given method :-

I've added a new Pad in my main menu called navigation...Where I've added all the button equivalent prompts i.e. Top, prev, next etc..

Skip for is having :-
type('_screen.activeform.iolinkedtoolbar') <> 'O' OR
! _screen.activeform.iolinkedtoolbar.cmdFirst.Enabled

& Selecting any prompt is having this command :-

_screen.activeform.iolinkedtoolbar.cmdFirst.Click()

Everything is working perfect... except I wanted to add one more option i.e. whenever the data entry form(s) becomes active, only then it should show navigation pad, rest of the times it should be hidden (instead of disabled)

Pls help...
