You did not provide a description of the shape of those zoom-in, zoom-out

Proposed text:
Often rendered as a magnifying glass with a "+" sign in its center for
zoom-in and with a "-" sign in its center for zoom-out.


dynamic-zoom: Adobe (in one of its application: IIRC, it was Acrobat
Reader) uses a cursor to allow the user to increase or decrease the
dimensions of objects like an image.

DHTML demo using it:


grab and grabbing cursors:
Those should be added into CSS 3 UI: grab and grabbing cursors help
indicate/reveal a draggable element in a drag-N-drop context and an
element being dragged, moved. Intuitively speaking, graphically speaking,
this cursor is much more natural, meaningful to users than the move "+"

(grab and drag the Position pseudo-titlebar)


Other cursors:
