Not really a questions but more a need: When I am in Canvas creating a table or just typing on a page and I need to copy and paste a section elsewhere and if I hit the backspace button by accident or delete the highlighted info, there is no way for me to undo the action. I would like Canvas to install a back button in the tool bar similar to Photoshop, Illustrator...maybe up to five back if needed. If there is a button/action somewhere I do not know about in Canvas if anyone could point me to it I'd appreciate it. 

Thanks!
