documentation: commenting multiple lines

[KiaraGrouwstra]

using amp for coding, one common operation is to comment (or uncomment) a selection of lines.
while amp's V mode lets the user select multiple lines, this can be used now to (un)indent those lines (#99), tho this mode appears to not yet facilitate operations like (uncommenting) or inserting/deleting texts at multiple lines at a time.
it would be nice if amp supported such an option as well.
