Only a short while ago (after about 100 years of use ?) I discovered that the CTRL + Q combination comments the line of code.
I immediately tried if the same combination on a line already commented would remove the apostrophe; it doesn't, so I looked at the menu (contextual, right click, more convenient) and the uncomment is done by pressing CTRL + W.
If it's not too much work, I'd prefer it to happen as I wrote, again with CTRL + Q (this way you only have to remember one combination and it would be easier if you have the cursor on the wrong line and want to "undo"), same as CTRL+B to set/remove a bookmark.
Obviously this is not of vital importance
P.S. You would save CTRL + W for other purposes
