I've done some searching, but haven't found anything promising so maybe someone knows. Is there any such thing as a layout that is tenkeyless, removes the nav cluster, but keeps the grouped function keys (and uses a layer for navigation)? Basically, a standard US101/104 layout minus everything to the right of F12/Backspace/Enter/etc. The 75% layout seems kind of close, but all of those seem to have function keys in one continuous row. Would it be feasible to build such a thing?
