A few days ago I had to adjust a text file. I needed it for testing with BizTalk whatsoever. In the Text file I needed to remove some columns and replace it with something else. Not sure what is was, but with Visual Studio it was a peace of cake.
Normally I use Notepad or Excel for this sort of action. I known there are other tools like Notepad++, but this is not installed on all my machines. NB That should be synced to in Windows 8.
Anyways, the Visual Studio editor has a lot of handy features.
Assume this text file, it is a dir listing.
To remove the first columns, put the cursor on the first column and press the ALT key. That is way easier than SHIFT ALT arrow right and repeat this for every line.
Press delete and the columns are gone.
To add some Text is done similarly. Cursor on the first column and press the alt key, move your mouse straight down en start typing.
Handy, more later.
