I wonder how much time I've wasted over the years

ctrl+backspace deletes the whole word

i never knew that, thanks

No problem. I always liked to learn about these little tricks. There’s also ctrl+up or down arrow that moves the text cursor to the beginning or end of the paragraph. Holding shift while doing so will select them and make it much easier to change your whole paragraph comment to a one-liner

yeah knew that one, using shift will select to that point also
