Yes, you would. I didn't mention keybinds yet, because I was tackling this
by parts.

I bind it to `C-;'. Another viable key might be `C-M-;'. But it definitely
needs a key.
When you want to comment/uncomment something between 1 and 9 lines, it
always requires less keypresses than the M-; alternative.

Besides, commenting a single line is such a common scenario, I find it
deserves a single key instead of a 4 key combo.

It's also something that a lot of IDE's assign to a hotkey, so I'm sure I'm
not the only one that finds it useful. :-) And people who come from other
editors are sure to miss it.
