Selector is also a handy tool to test regexps, or to display menus
with many possible choices. For the latter, the -x option allows to
-specify a label delimiter: the part of each line before that character
-will appear during the selection, but only the part after that
-character will be returned.
+show different strings than the ones returned.
Note that because this is an interactive command, the standard input
can not be used as one of the input files.
