@MaDill The Find/Replace dialog box does save some number of recent searches; however, it does not allow you to save favorites like the program you used appears to. I know there’s been some discussion on how many searches can be saved, and how to possibly increase that.

It’s not a bad suggestion, but some users posting here claim that each RegEx is generally unique. However, I for one, do like to have someplace to start when I create a RegEx. Currently, I use a text file with significant RegEx strings and descriptions of them. A limited number of “favourites” would be helpful.

Also the favorites in the search I used at that time a lot

When you not need the regex frequently then it is a nice hint to get back in the syntax.

You can also use the simpler “\R” to represent any of the various forms of line endings.

Some codes or characters are difficult to remember, then as a suggestion for notepad ++ developers, in the field search please add a table of characters for the purpose of easily paste them

Search > Replace (often mapped to Ctrl+H)

• Find What: “[\r\n]” => find either CR or LF
• Replace With: " " => Replace each CR or LF with a space
• Search Mode: ☑ Regular Expression

(the quotes are there to make the space obvious; don’t include the quotes)

However, that will cause windows-style EOL (CR+LF) to become two spaces
If you want a CR+LF to become one space, while still converting singleton CR or singleton LF to one space, change to

• Find What: “\r\n|[\r\n]” => find either CR+LF or CR or LF
  (keeping the other options the same)
