The easiest and most effective way is to make your triggers more precise. If you know the punctualtion will always be at the beginning or end of a line, modify the trigger to include the punctuation.

Click on "convert to regular expression". For your example that gives this:


^(.*?) the (.*?) (.*?) has just left$


Then you can make it more precise. For example an optional thing like *> could be added at the start:


^(?:\*\>)?(.*?) the (.*?) (.*?) has just left$



The extra bit I added (in bold) looks for 0 or 1 occurrence of *>. I "escaped" them with a backslash because the * (at least) has a special meaning in regular expressions. The ?: at the start says to not make it a wildcard (so wildcard %1 is still the same thing).
