MODE: bound to ROOT > MODE
STAT: bound to ROOT > STAT
MATH: repurposed to be HOME (aka ROOT)

Should the STAT group be worded ?
STAT: bound to ROOT > [down arrow] > STAT

That's not how a hierarchical menu system or file system is normally understood. Consider the following tree of files:

Code:
FolderA
|-- itemA1
|-- itemA2
`-- FolderB
    |-- itemB1
    |-- itemB2
    `-- FolderC
        `-- itemC1

To refer to itemC1 using its full path, one would write:

FolderA > FolderB > FolderC >itemC1

not

FolderA > down > down > FolderB > down > down > FolderC > itemC1

In the file hierarchy above, each line contains only one item or folder. In RPN83P, each line can hold up to 5 items or folders. So visually, it looks like:

Code:
FolderA
|- itemA1 itemA2 itemA3 itemA4 itemA5
|- itemA6 FolderB itemA8 itemA9 itemA10
              |- itemB1 itemB2 itemB3 itemB4 itemB5
              |- itemB6 FolderC
                            | itemC1

To refer to itemC1, it is still "FolderA > FolderB > FolderC > itemC1", even when 5 items of each folder are displayed per row, instead of a single item per row.

Does my Menu Hierarchy diagram help in any way? Are you having a similar difficulty with the menu system on the HP-42S/Free42? Because RPN83P basically implements the same system.
