Being left-handed, I use the mouse in my left hand. In most applications I use Ctrl + Insert or Shift + Insert to copy and paste (with my right hand).
For some bone-headed reason, this is not supported in Photoshop, so I have to use right-click > Copy sub-menus, which is a lot slower.
Is there a way to configure Photoshop to use Ctrl + Insert to copy and Shift + Insert to paste?
EDIT: I tried editing keyboard shortcuts, but it will not accept CTRL + INSERT as a valid entry.
Is there no valid option for left-handed users?
