The same way anyone under 2k rep makes a suggested edit; by clicking on the edit
link under the post (albeit that it's called improve this question
when visiting the site when not logged in).
Anonymous visitors are allowed to suggest edits on posts that are at least 10 minutes old.
Unregistered get improve this question
or improve this answer
link instead of edit
.
And as Martjin Pieters they can suggest edit same way anyone under 2k rep makes.
Test test this open any (atleast 10 minutes old) Stack Overflow question in private browsing or incognito window. You will see there improve this...
link instead of edit
.
And yes if their suggested edit get approved, that edit is shown as edited by Community ♦ Moderator user.
