+<<.link-badge-added "https://github.com/Jermolene/TiddlyWiki5/pull/7710">> a new [[shortcut syntax|Conditional Shortcut Syntax]] for concisely expressing if-then-else logic. For example:
+
+```
+<% if [<animal>match[Elephant]] %>

+	It is a giraffe
+<% else %>

+		<$text text=<<currentTiddler>>/>
+	</$list-template>
+	<$list-empty>
+		None!
