Command

ebyxb*Rv""Nn<alt-)>

%s`+j<enter>f;<alt-(>

1. eb selects the next word and trims whitespace
2. y copies the selected word and yanks it into the " (double quote) register
3. xb selects the last word in the line
4. * sets the current selection as the search pattern
5. R replaces the selected word with the copied selection from earlier
6. v enters select mode
7. "" selects the " (double quote) register. Pressing N will add a new selection at the previous occurrence of the word saved to the register
8. n adds a new selection at the next occurrence of the search pattern assigned earlier
9. <alt-)> rotates the contents of the selections forward
10. % selects the entire contents of the file
11. s brings up a prompt to select sub-selections by a given regex. We type in `+j for the regex and select all matches with <enter>
12. Since we're still in select mode, typing f; moves each cursor to select up until (and including) the next occurrence of a semicolon
13. <alt-(> rotates the contents of the selections backwards
