Right now we have for the mouse conf. :
Settings/Interface/mouse
1-Left button
2-Left button + CTRL
3-Middle button
4-Right button
5-Right button + CTRL
6-Mouse wheel
7-Mouse wheel + CTRL
5 Customs chooses possibles:
@1-Zoomed selection
@2-Make selection
@3-Zoomed selection ==> "/" ==> or "Last zoom level & area used"
@4-Move picture
@5-Move picture
@6-Zoom in/out
@7-Zoom in/out
(or Do nothing)
... And I would like to have ( the "/" and the "*" keyboard zoom functionalities available too as option for the mouse) ... "/" for meet to the window, and the "*" for a future scale 1:1 (100% zoom) ... and a "last zoom level and area used" choose too

Because, I like switching between "Zoomed selection" and " "/" for meet to the window" for detail in pics.
