+    modifier syntax:
 
-        i => case insensitive
+        (?MODIFIER)
-        ! => negative match
+
+    The most important modifiers are:
+
+    "i" ignore case "m" multiline mode "s" single line mode
 
     Example for a case insensitive search:
 
-        kubectl get pods -A | tablizer "/account/i"
+        kubectl get pods -A | tablizer "(?i)account"

-
-        cat table | tablizer foo '/bar/!'
-
-    This would match a line "foo zorro" but not "foo bar".
-
-    The flags can also be combined.

-  INTERACTIVE FILTERING

-  PUT FIELDS TO CLIPBOARD
-    You can let tablizer put fields to the clipboard using the option "-y".
-    This best fits the use-case when the result of your filtering yields

-        cloudctl cluster ls | tablizer -yid matchbox

-    If "matchbox" matches one cluster, you can immediately use the id of
