IntelliShell doesn’t seem to have a good “change variable name” feature. Search & replace sadly doesn’t have something like “exact match” or “match entire word”, which would be kind of a MVP for that kind of feature.
If I have two variables like syncSchool and syncSchoolNumber and later I decide that syncSchool should be syncSchoolId, I can’t use search & replace anymore, because every “syncSchool” finding would also find syncSchool within syncSchoolNumber and would mess this variable up. So I have to do it by hand. “Match entire word” (Visual Studio Code) / “Whole word” (Sublime) enable me to find just syncSchool, without syncSchoolNumber and only change these occurences.
