Currently Inkscape uses Alt-Click for various things (select-under, randomize star, etc.) However, generally this shortcut is taken by the desktop environments. In fact we have a bug in our tracker and in Ubuntu's tracker:
http://sourceforge.net/tracker/index.php?func=detail&aid=1250110&gro...
It is possible for the user to recover this shortcut for Inkscape by disabling it in the desktop environment's configuration settings, but this has the obvious downside of disallowing the shortcut for other programs beyond Inkscape.
In playing around with it a little, I notice that Alt-Ctrl-LeftClick appears to produce the same behavior as Alt-LeftClick. Since Alt-Ctrl-LeftClick is not taken by the desktop environment, there is no conflict.
Thus it would seem that we could address the bug easily without any code change to Inkscape, by simply altering the documentation to indicate use of Alt-Ctrl-LeftClick instead of Alt-LeftClick. For users who prefer the Alt-LeftClick behavior, that will remain working so no functionality is lost.
What do others think of this approach?
