+If you don't want to define a rule, you can do the same with the following
+command:
+
+```vim
+" Using regular expression /#/
+" - "is" is fuzzy-matched to "*i*gnore*s*"
+:EasyAlign/#/{'is':['String']}
+```

+In this case, the second line is ignored as it doesn't contain `#`. (The one
+highlighted as String is ignored.) If you don't want the second line to be
+ignored, set `g:easy_align_ignore_unmatched` to 0, or use the following
+commands:
+
+```vim
+" Using predefined rule with delimiter key #
+:EasyAlign#{'iu':0}`

+" Using regular expression /#/
