Any objections?
control click on OS X has always been used to bring up the [properties/open/help] dialogue.
command (applemark) E has always been standard for edit mode.
personally, i'm finding the command-click function really annoying, especially when used in conjunction with other command functions (cut paste etc)
but if you change it to control-click, what happens to the [properties/open/help] dialogue if you are not in edit mode?
