indentation of a block of lines

[mareb]

I do not found the command for doing this:
paste a block of lines in a source file and make an un-indentation (cut spaces on the left).
On most editors it is Strg-Shift-I or Strg-Shift-Tab

Another usefull command, I did not found, is the marking (with copy & paste) of a block of columns (over lines).

Thank you in advance

Alt-Ctrl + Arrows will allow you to select columns
Or use
Alt-Ctrl mouse left click

To indent block, select the block and use TAB or Shift-TAB? is this what you mean?
