Blink: shift-tab does not work

[goerz]

One of my vim plugins uses the key-combination shift-tab to convert latex sequences to unicode (in command mode in vim). In Blink, this does not work. The combination seems to have the same effect as pressing tab by itself: it inserts ^I. Actually, this by itself is also different from what happens when I do the same thing on my laptop (a tab key does nothing there).

You can reproduce this by using my vimrc, opening a new file in vim, :set ft=julia, and then :/\alpha<shift><tab> which is supposed to produce :α, but produces :\alpha^I instead.

@goerz thank you for your feedback.

It is already fixed and will be available in next TF.

Ref #117

I can confirm this working in today's Testflight release.

Shift + tab doesn't work again, it seems.

I've tested this on the most recent version, built with Xcode from the repo obtained via the commands:
git clone --recursive https://github.com/blinksh/blink.git && \
cd blink && ./get_frameworks.sh

Please advise. Thank you in advance.

Hi @lev-kusanagi,

Just test it and it works for me. What kb you are using?

[lk251]

Hi @yury thanks for your reply. I’m using the Thinkpad Bluetooth keyboard with Trackpoint.

Hi @lev-kusanagi,

Please run showkey command and paste output here.

And if it possible, please check it other apps. For instance, in numbers.app tab selects next cell and shift+tab it selects prev cell (see video). Does it work with you kb?

[lk251]

showkey outputs:
When pressing just the tab key:
\t 9 0011 0x09
When pressing shift + tab:
^[ 27 0033 0x1b
[ 91 0133 0x5b
Z 90 0132 0x5a

Yes, in numbers.app, tab selects the next cell and shift+ tab selects the previous cell.

Thanks again for the help.

[yury]

So, everything seems ok to me.

What app within blink don't work properly with shift+tab? I tested with zsh completions.

Hi @yury, the probem occurs while using emacs, sorry I forgot to mention that.

Specifically, I noticed the problem while using org-mode.

[yury]

Hmm, I'm not emacs user. But when I try to press shift+tab in emacs it prints <backtab> is undefined (Don't even know what mode I'm in :) ). So emacs see that shortcut and recognize it for me.
Didn't setup anything, just brew install emacs.

/cc @carloscabanero as emacs guru :)

[lk251]

@yury Ah- emacs in ubuntu 16.04, i forgot to mention!

Still- Interesting! sounds better than what I get (i types out a Z right now :D)
@carloscabanero te invocamos! ayuda por favor :) My emacs brother :D

[lk251]

@yury should I open another issue? Cheers.

[yury]

Oh, I forgot, I have installed emacs24 on ubuntu and I get is undefined too...

I don't think we should create new issue. Carlos will answer as soon he have time.

@lev-kusanagi I was actually going to suggest you to try using org-mode. In my case it is collapsing the sections. Can you do a M-x describe-key and see what it returns? In my case, within org-mode:

<backtab> runs the command org-shifttab (found in org-mode-map), which is an                                                                   
interactive compiled Lisp function in ‘org.el’.

thanks @carloscabanero ! app is crashing on launch now, even after rebooting. will post the result of describe key after i sort that out! (any tips welcome of course)

[lk251]

@carloscabanero M-x describe-key outputs "M-[" , when typing Shift + tab

[lk251]

@carloscabanero also, in org-mode as well, Alt + Enter (M-RET) produces just "RET" in M-x describe-key

[yury]

Hi @lev-kusanagi,

How did you fix crashes? And may be you know what cause it?

Thank you.

[lk251]

@yury Sorry, I've been traveling! I haven't solved the crashes, it still happens. I think I'm going to rebuild and reinstall it, and hope for the best. Is there already an issue for this? Otherwise I should open one.

@carloscabanero does that output from M-x describe-key make any sense? That's probably the reason it isn't working.

[yury]

Hi @lev-kusanagi,

Yep, please try latest from raw branch. And if it crashes for you, please feel free too create new issue.
Thank you.

[lk251]

@carloscabanero @yury Apologies, I've found out that it's an Ubuntu terminal problem, it happens when running emacs from terminal (no GUI). I heard urxvt didn't have this problem, but I tried it and it still had the issue (Shift + Tab results in M-[)

[lk251]

@carloscabanero I suppose the question is- which terminal do you use?
