It would be really cool if there were a method for each of the Actions (from the ribbon bar) that would "comment out" the current line and those nested.
Currently you can do they by adding a comment action, going through the hassle of moving it to the desired location, then nesting the line you really want underneath it. To un-comment you have to move the desired line outside the comment, and then delete the comment action. This is a LOT of clicks just to comment out a single line of code (OK, possibly more but you get the idea.)
Commenting-out code should be a single click.
Two suggestions for this.
1. in the UI, place a comment icon next to the trash bin icon on the left.
2. add a checkbox "in" the Action item down below the escape code choices.
