Dedent selected block in text editor

In the text editor, if I select text and tab the text is indented, but if I shift-tab it is not dedented. Is there a key combination for dedent-ing a block of selected text? Thanks,


I am on Mac and I use command-square bracket to move blocks. Use right square (]) bracket to move right and left ([) for left. I think Ctrl- would replace command key on Windows.

Thanks, Ctrl-[ Ctrl-] do work. Is there any way to configure this to use Shift-Tab? At least for me I need two hands to use the Ctrl-[ / ] combinations.

For the classic notebook interface the guide to configuring the shortcuts is here. I note in JupyterLab, the place to alter the shortcuts is under Settings > Advanced Settings Editor > Keyboard Shortcuts.
