   You didn't provide this crutial information, but from the fact that you only get a single TAB back, I assume you are on windows?

   Windows doesn't modify the tab-key when pressing shift, it always just reads TAB. So it is imposible to use TAB+SHIFT on windows, this has nothing to do with readchar() but is simply a windows limitation.

   We could add it to the Linux side, but I would still not recomend using it as it is not portable...

   I'm use macos. It’s a pity that it won’t work for Windows, of course I want a cross-platform implementation. But support for *nix would also be nice.
   If you think about support in windows, is it possible to have a solution for a power shell or a windows terminal? As a last resort, there is wsl or cygwin.

   For *nix support

   This will have to wait but will probably come at some point. For now the project maintainer is not responding and untill he does I am just a powerless contributer myself. You can however, for the ime beeing, patch the key-module for unix systems with this line after your readchar import:

   from readchar import readkey, key
   key.SHIFT_TAB = "\x1b\x5b\x5a"

   Now you can use it as expected:

   while True:
       k = readkey()
       if k == key.SHIFT_TAB:
           print("got macro shortcut!!!!!")

   You can get the codes for other unsported keys by running my testing script, it will print you the codes for all pressed keys.

   For windows support:

   readchar relies on the standart libary msvcrt to do the actuall terminal interaction. If you take this exapmple:

   from msvcrt import getch
   
   while True:
   	k = getch()
   	print(k)

   you will see that both pressing TAB and SHIFT+TAB result in the same output of b'\t'. Windows doesn't provide this keycombination to python so it is imposible to handle it.

   Thanks for your answer. I found why I can't use readchar.readkey(), it's #11 problem. Pycharm terminal != system terminal. In system macos term i can read shift+tab.
