I also wanted to document the cool feature of blocking multiple lines / typing over multiple lines. This comes in very handy more often that I would have thought!
Also, I changed my default setting for RegEx to use POSIX. Otherwise you need to escape the parens (which I find incredibly hard to read)
If you want to do the same- you can edit your user.properties file with the following two lines
#### Changing Replace to posix regular expression mode so do not have to escape parens
Anyway, if none of this makes sense (but sounds interesting) I have the Find and Replace Scite video here.
And here are a couple of helpful pages with:
SciTE RegEx documentation
Here are some useful POSIX terms which are more readable: [:xxx:] were xxx is one of the following words:
alnum letters and digits
digit decimal digits (like \d)
lower lower case letters
punct printing characters, excluding letters and digits
space white space
upper upper case letters
word "word" characters (like \w)
