In both this comment and the previous one you describe issues which do not exist on a TenKeyLess keyboard. You must be confusing TKL with other layouts.

On a TKL setup, the arrow keys are not cramped, they're full size and precisely where they're supposed to be.

The PgUp PgDown Home End (and Ins-Del, since that's the rest of that 6-key block) are full size and not cramped, and also precisely where they're supposed to be.
