 When working with a group of people in a workshop, sometimes you need to decide on a subtopic (i.e., selecting one of the proposed items). After discussing them, people can vote "yes" or "no" for each item. You can add a positive point for each "yes" (`=`) and a negative one for each "no" (`-`). In the end, you can press shift+t to sort them and see the highest-ranking choices on the top.
 
+Another way of ranking is to use stars. To do so, you can press `alt+up` or `alt+down` to add or remove stars and show a zero to five rank.
