1- There is an option in NP++ to hold Ctrl while clicking in multiple locations in the text file, so the cursor stays there for multi-editing. I want to know how to de-select a clicked location?

I tried clicking with alt, or shift but they don't work.

2- Also, is there a way to auto put the cursor on a specific character in all the document? Without having to click on each one while holding Ctrl?

Example: searching for the word "Ipsum" for example puts the cursor at the end of the word or whatever:

Once you have installed Perl, you can run any script in command line like this:

perl path/to/script.pl

or, for a oneliner:

perl -e 'the instruction' pathtoinputfile > pathtooutputfile 

In your case, you have to read a file and write the result in an another file:

perl -ane "while(/bIpsumb/g){$i++;s/bIpsumb/$&$i/};print" inputfile > outputfile

If you want to to the replace inplace (i.e. replace the file):

perl -i.back -ane "while(/bIpsumb/g){$i++;s/bIpsumb/$&$i/};print" inputfile

This will backup original file in original.back
DON'T RUN TWICE without revert the original file.
