Changing code indentation levels automatically or manually [duplicate]

Add increase/decrease tab indent buttons to the editor toolbar

If you have some code which is heavy nested and you just copy some of the inner code you end up with a lot of useless space (if you don't have box-selection or don't know how to use it at least).

So wouldn't it be convenient if the "greatest common whitespace" in pasted text would be removed from each line automatically? Or if that is not going to happen how about two buttons which add/remove 4 spaces to/from all selected lines?

(Edit: I know you can use the normal code block button to shift code back but not all people do, and having a right shifting button would be nice for fixing code-internal indentation problems or if you paste a segment into the existing code and you want to line it up properly)

Answer 1

You can highlight the code and use the code format button to shift all code back. It will basically tab the code back.

Works great most of the time, unless the tab levels are way off.

Try editing my answer. If you highlight the code below and click the code format tool once it will shift to the proper place. Click it a second time and it will shift flush left.

Important Note
As in the comments below found that you must ensure all white space in from of first line is selected.

    //Some Code
    if (myTab >= TooMuch) {
        shiftLeft();
    }

Test 2:

        //Some Code
     if (myTab >= TooMuch) {
        shiftLeft();
     }
