Selecting lines in nano can be achieved using Esc+A. With multiple lines selected, how do I then indent all those lines at once?

    Highlighting is working now by just using Shift + Arrow-Up or Arrow-Down at least since Nano version: 2.9.1 – nath Jan 9 '18 at 12:08

Once you have selected the block, you can indent it using Alt + } (not the key, but whatever key combination is necessary to produce a closing curly bracket).

    I am trying this without success on OSX Mavericks. Instead pressing alt+} results in an opening (or closing depending on whether shift is held down at the same time) quote character being inserted. – Ben Dec 22 '13 at 15:56
  • @Ben It works for me, perhaps your terminal emulator or window manager is eating the meta key? I don't know about how the OSX terminal works, though. – Chris Down Dec 22 '13 at 15:58

    @Ben From a quick Google it seems that the Mac terminal is the culprit, see here: blog.remibergsma.com/2012/01/30/… (for future readers, the solution: Terminal > Preferences > Settings > Keyboard > Check "Use option as meta key") – Chris Down Dec 22 '13 at 16:00

    Alt + } didn't work for me, could be my putty settings, however Alt + Shift + { did! – jtzero Jun 12 '14 at 14:15

    @David Alt + { :-) – Chris Down Aug 3 '15 at 7:22

If you're using macOS and haven't reset your meta key in the terminal, the command for this will be Esc+}
