Comment 8 for bug 438603

As far as I can tell this is a problem in Inkscape, not upstream:

- 'Cmd' instead of 'Ctrl' works e.g. with the GTK+/Quartz package
   of Bluefish [1]
- in Inkscape, no keyboard shortcuts are listed in the menus from
  the global menubar (they are listed in the context menu of the
  canvas area)
- even if 'gtk-key-theme-name = "Mac"' is set in the used gtkrc
  file (and the corresponding gtkrc file installed/loaded), the
  keymappings only work e.g. in Inkscape's gtkfilechooser, but not
  on the canvas area or any other Inkscape widget.
  Seems to me that Inkscape does its own thing about detecting and
  handling the modifiers. Currently, 'Cmd' acts as 'Alt' key if
  Inkscape is built with GTK+/Quartz [2]

    acts the same as 'Alt' under X11, whereas the real 'option/alt'
    key doesn't seem to be recognized by Inkscape.»).
