Jak vybrat kód mezi taky v Notepad++
How to select f.e. javascript tag contetn in Notepad++
- insert content between braces
- put caret behind the last bracket
- press Ctrl + left Alt + B or Ctrl + Shift + B to control the first brace

< script>
{
var bla = 0;
// bla bla ... long content
}  // place caret/cursor behind the last brace { and press  Ctrl + left Alt + B (Notepad++)
< /script>

At Settings->Preferences->Delimiter, change the delimiters
from parentheses to braces and check the multi-line box.
Then you can Ctrl-double-click on either brace to highlight everything in between.
