 ## Configure optional and additional marks
 
 Here comes some inspiration for additional marks you could enable. Some
 are potentially disturbing and are not pre-configured for that reason:
 
-    let g:karlmarks  =   '"'  " position in buffer when left
-    let g:karlmarks .=  '{}'  " start/end paragraph
-    let g:karlmarks .=  '()'  " start/end sentence
-    let g:karlmarks .=  '[]'  " start/end sentence
-    let g:karlmarks .=  '.'   " last change
-    let g:karlmarks .=  "^"   " insert mode stopped
-    let g:karlmarks .=  "'`"
+```vim
+let g:karlmarks  =   '"'  " position in buffer when left
+let g:karlmarks .=  '{}'  " start/end paragraph
+let g:karlmarks .=  '()'  " start/end sentence

+let g:karlmarks .=  '.'   " last change
+let g:karlmarks .=  "^"   " insert mode stopped
+let g:karlmarks .=  "'`"
+```
 
 but the `g_karlmarks` setting defaults to
 
-    let g:karlmarks = "<>"
+```vim
+let g:karlmarks = "<>"
+```
 
 to allow easier modification of the last selected block, e.g. reposition the
 start of the block with `m<` and use `gv` to show the new selection.
