Replace all instances of a character at a specific location

[adame]

I need to replace all instances of a character at a specific location on a line of text. For instance, I need to replace all instances of the 106th character in the line below with the same chacter followed by a newline (\n). I have tried recording a macro and copy/pasting into the search function, but the macro seems to remember the search terms, not replace them each time the macro runs.

Here's the line of text, in this case, I need to replace all instances of "\" but this could be any character, such as "~" or "+", etc.

Dear Adame,

Try this (no POSIX):

Change

(\.\{105\}\)(\.\)

into

\1\n\2

RE on.

I guarantee nothing, but it seemed to have worked with me. Maybe I left out one or two parentheses; but something like this should do the trick.

That puts a newline before the 106th character. The original poster seems to be asking how to insert a newline after the 106th character. That can be done simply like this:

Find what: ^.{106}
Replace with: \0\n

[X] Regular expression

or

Find what: ^(.{106})
Replace with: \1\n

[X] Regular expression

These assume you are using Posix regular expression syntax, which makes for rather more readable regexes:

Configure | Preferences | Editor

[X] Use POSIX regular expression syntax
