At present it is possible to assign a keystroke to comment the current line and another to uncomment the line. I would like to see an option to toggle comments on and off instead/as well. So if a line is already commented out, it will be automatically uncommented, and vice versa. It would mean that I only need to assign one key-combination to comment and uncomment, instead of two.
Oh, by the way, it would also be nice if I could just comment where the cursor is, without needing to select a block of characters, ie just go to the line I wish to comment and press my key-combo and have the line comment out/in
