Quiet-Q Option
You may append one or two option letters to a command name: J, T, and Q. For example, the Add command has these variations: AddQ, AddT, AddJ, AddQT, and AddQJ. The Q option means QUIET, without line numbers, or without printing the lines processed. For example:
/lq 5/10 {list lines 5/10 without line numbers}
/kq paul {save lines without line numbers}
/aq 5.01 {add new lines, but don't prompt}
/aq 10.00=abc {add file without printing the lines}
/hq 45.1/.9 {replace Hold, but don't print lines}
/cq "X"Y" {change X to Y, but don't print line}
