I'm a left handed mouse user. For editing purposes, I don't use my left hand, I use my right hand. And, generally use the right handed keyboard shortcuts as defined by Microsoft a long time ago. I've notice that some of the short cuts have been implemented, while others are not. It is possible to implement them all, as it's annoying when I try to do a copy and paste operation, and have to .. Left Click .. my mouse to execute a copy operation, while pressing [ SHIFT + INSERT ] to do the paste operation. I would prefer to just press [ CTRL + INSERT ] to copy.
PS .. I've also noticed that [CTRL + END] works, while [CTRL+ HOME] does not.
