Bear in mind that *a lot* of consoles in StarTrek are in at least two parts (think of the stations at the back of the Enterprise-D bridge), not "only a touch-screen" at all.
This construction lends itself to any "keyboard and monitor" analogy that;s needed in any particular circumstance (doesn't Data use a QWERTY keyboard in "penpals"?) - only the keyboard's reconfigurable to whatever best suits the user's needs.
There's a QWERTY in "Pen Pals"? I've been trying to spot one in Trek for decades, and I thought JJ Abrams' Star Trek
was their first appearence on a starship.
