This regex he | she selects he or she (with one space before and after):
how he just he just
when she just she just
Can I exclude selection if a word how or when stands before? I mean select only second column in the example above.

Usually, a negative lookbehind does this job. If you have trouble with that, please edit the question with your current regex. – Wiktor Stribiżew Mar 26 '20 at 12:18

`\w*(?<!how) he | she ` It's not selecting what I ask in the question. – F. Vosnim Mar 26 '20 at 12:21

Certainly, you do not have any word chars there, you do not need `\w*`. Besides, after `how` and `when` you havbe a space. You should account for that in the lookbehind. Also, if you want to apply one or a series of lookbehinds to two or more alternatives, group them. – Wiktor Stribiżew Mar 26 '20 at 12:23
