Questions
How do I replace line breaks or tabs?
Type \n for a line break and \t for a tab in either field: “\n\n” finds blank lines. With “Regular expression” on, \s and the other classes work too.
How do groups work in the replacement?
With “Regular expression” on, $1, $2… put back what the brackets caught, $& the whole match, $<name> a named group. Find (\d+)\.(\d+) and replace with $2.$1 to swap the parts. Without it a $ is just a $.
Does “Whole words” work for Russian?
Yes: word edges are found by Unicode letters, not only Latin ones, so “кот” does not match inside “который”.
