Enable block de-indent (shift+tab) in text editor?

[johnmarktaylor91]

I love the ability to highlight and de-indent a block of text in the Notebook editor with shift+tab. However, this feature doesn't seem to work in the text editor (i.e., if you do File->New->Text File)... would it be simple to add?

This would be a big plus. I badly need this right now since I am trying to make jupyterlab as my main work env hosted on a remote VM.

Was surprised when I can't de-indent parts of my SQL script.

The same here

[BXSuhelSingh]

Yeah same here

Block indent works, would be great to get de-indent as well

[gavieira]

I definitely agree

Actually, I just found out that Ctrl-[ works for block dedenting.

However, this shortcut did not work for me in chrome (probably due to some extension). Switching to another browser fixed the issue.

Also, it seems relatively straightforward to customize the shortcut and replace it with shift+tab.

Thanks, this worked for me in Chrome (Version 79.0.3945.79 (Official Build) (64-bit)). I am on a Mac, so Cmd-[ dedents, Cmd-] indents in a python script and a notebook.

Definitely a must, 'tab'-ed multiple lines, how to 'shift-tab' back?

Strange that this works in notebook cells (which use codemirror) but not text editors (which use codemirror)...

Probably just needs a config fix somewhere

Hah! I got it. It's the same problem that I fixed for the notebook and console waaay back in #5060: the 'shift tab' shortcut is also being used for the command to launch the interactive help tooltip. What's meant to happen is that if you just place the cursor at, say, a python keyword, 'shift tab' will open a tooltip with the relevant docstring; but if you have text selected and then hit 'shift tab' you get a de-dent.

This is indeed what happens in the editor in notebook and terminal. However in the text file editor, for whatever reason, the tooltip command is currently swallowing the 'shift tab' shortcut even when text is selected. I'll see if I can fix it

update

This will be fixed by #7865

That 'shift-tab' is not working, so I have to press Ctrl-Z

[telamonian]

To clarify, shift tab to dedent will be fixed in either JupyterLab 2.0.0 (which will be released very soon), or one of the early 2.0.x releases, depending on when #7865 gets pulled in
