Highlight specific keywords in the terminal as they appear

As an additional usage of the selected answer, I'd like to suggest adding a tigger for "smart quotes" with the regex [”“’‘]

Example of iTerm2 > Preferences > Profiles > Advanced > Triggers > Edit

This will save you some day when a coworker sends you a line of code via a chat mechanism (like Slack) and the quotes get automagically "improved". The trigger won't fire as you paste/type them, but they will happen after the line scrolls up your terminal. So, it won't prevent the mistake, but it will save you time wondering why the command failed.

Example of triggered smartquotes


A Profile-based trigger can highlight as much or little of a line as you choice (via the regex).

To highlight just a "word" in a line, you can create a simple Highlight Text trigger, i.e.:
