If you really want such specialized functions hardwired into the keyboard, AFAIK, you are going to have to make your own custom keyboard. Otherwise, you could use application-specific keyboard commands using a standard keyboard.
Something that comes close to the layout you have indicated (without the word-processing-specific keys) is the Leopold FC660C (Topre switches) or FC660M (Cherry switches).
My own favorite layout in a 60% form factor is the HHKB Pro 2. Even when I am using a standard keyboard, I remap the keys in the HHKB Pro 2 layout.
Good luck!
