+#### coffee\_indent\_keep\_current
+
+By default, the indent function matches the indent of the previous line if it
+doesn't find a reason to indent or outdent. To change this behavior so it
+instead keeps the [current indent of the cursor][98], use
+
+    let coffee_indent_keep_current = 1

+*Default*: `unlet coffee_indent_keep_current`
+
+Note that if you change this after a coffee file has been loaded, you'll have to
+reload the indent script for the change to take effect:

+    unlet b:did_indent | runtime indent/coffee.vim
