Thinking about it some more, when we are in interactive stack mode, we have the whole keyboard to our disposal, so we could simplify your idea a bit, using less shifted keys. We'll also have the top soft menu available at our disposal.

So the cursor up enters interactive mode. Once there:

Navigation:
* Right-shift up/down goes to top/bottom of stack
* Left-shift up/down moves by pages.
* Up/down just move the cursor.

Selection:
* Select/deselect an item could be +/-, or Space, or Enter (or all of them).
* Perhaps the + key could select/deselect all items below the cursor, until either level 1 or the next selected/deselected item.
* Perhaps the - key could select/deselect all items above the cursor, until either the last used item in the stack, or the next selected/deselected item.

Move/Copy (move=right cursor, copy=left cursor, always consistent):
* Right cursor moves selected items at cursor position.
* Right-shift Right moves selected items to top of the stack (bottom of the stack as seen on the screen).
* Left-shift Right moves selected items to bottom of the stack (top of screen).

* Left cursor copies selected items at cursor position.
* Right-shift Left copies selected items to top of the stack (bottom of the stack as seen on the screen).
* Left-shift Left copies selected items to bottom of the stack (top of screen).

Rotation:
* Alpha-up "rotates" the selected items up one level (if there's no selection, automatically use between level 1 and current item).
* Alpha-down "rotates" the selected items down one level (if there's no selection, automatically use between level 1 and current item).

It's basically the same, with different key assignments. Any comments?
