Why does this regex require an additional "case-sensitive" option?
Like a different regex, but it also has the same application, so why are there two types?
[A-Z] = big and small letter match
[a-z] = big and small letter match

Case sensitive option is part of the regular expression. You can switch it on/off.
PSpad does it in Search dialog, if you use regular expressions in script, you need to set it by your own

Hi, for whole word, you could try to search for "(?-i)\b[A-Z]{2,}\b", if you want to find even letters alone, it's simpler "(?-i)\b[A-Z]+\b"

^(?-i)[A-Z]+$

You can use two more options, but one of the options unfortunately does not work, so you have to add ^ $
