     markdown which prints a Markdown table, yaml, which prints yaml encoding
     and CSV mode, which prints a comma separated value file.
 
+  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
+    just one row. For example:
+
+        cloudctl cluster ls | tablizer -yid matchbox
+
+    If "matchbox" matches one cluster, you can immediately use the id of
+    that cluster somewhere else and paste it. Of course, if there are
+    multiple matches, then all id's will be put into the clipboard separated
+    by one space.
+
   ENVIRONMENT VARIABLES
     tablizer supports certain environment variables which use can use to
     influence program behavior. Commandline flags have always precedence
     over environment variables.
 
-    <T_NO_HEADER_NUMBERING> - disable numbering of header fields, like -n.
+    <T_HEADER_NUMBERING> - enable numbering of header fields, like -n.
     <T_COLUMNS> - comma separated list of columns to output, like -c
     <NO_COLORS> - disable colorization of matches, like -N
