Answer 1

• Ctrl+H to open the replace dialog
• Find what: .*
• Replace with: empty
• Search mode: regular expression, with . matches newline not checked
• Replace All

.* means searching for a space ( ) followed by any characters (.*). Regex matches greedily by default so it'll match everything from the first space until the end of line

You can also target the first word instead with: ^([^\s]*)\s.*$
and replace with: \1.
