Could you suggest model of minimalistic functional keyboard?
I want it be without margin,

numpad is on letter keys(activated by Fn),

and "insert".."page down" should be in vertical row or as additional functions of another keys too.

I've got idea: emulation of numpad on letter: it is necessary to edit config files of your layout, so just minimal keyboard if enough withtout Fn.
