It simply matches for those symbols: ~!#$^*!&()`(_+{}|:"'<>?/,-=.[]\n\t\r

\n - New line symbol
\t - Tab symbol
\r - New line symbol

  • BTW, I'm sure there is a typo in this regular expression, the author has forgotten a backslash in front of the minus sign. So instead of matching just a comma, minus sign, and equal sign, `,-=` matches all characters between comma and equal sign. – Alex Sveshnikov Mar 04 '20 at 08:00
  • FYI: `\n` matches a linefeed and `\r` a carriage return (nothing to do with “DOS mode”). – Toto Mar 04 '20 at 10:07
