Can't insert + or * (plus or asterisk) characters

[dangirsh]

Thanks for this package! vterm in Emacs is now my primary terminal.

I find that I can't insert the + or * key anymore. Not sure what changed, or how recently. Pasting in these characters works, and characters ^=&!@#$~{(<>)]}%/\';|:". and backtick all work fine.

Any tips for debugging this greatly appreciated!

What is the output of C-h +? Can you reproduce with emacs -Q?

[dangirsh]

C-h + is undefined.

Assuming you meant C-h k +, that's (vterm--self-insert), which other characters are also bound to, including *.

The problem reproduces exactly with emacs -Q

Specifically, in a fresh emacs -Q, I ran:

(add-to-list 'load-path "/home/dan/.emacs.d/.local/straight/repos/emacs-libvterm")
(require 'vterm)

It then asked me to recompile the module, which I did.

The ran (require 'vterm) again, which opened a terminal window. Neither the + or * keys would insert characters.

[Sbozzolo]

Thanks, I meant C-h k +. I am surprised that the problem occurs with emacs -Q. Could it be that your system is capturing + and * for some reason? The other possible explanation is that emacs28 is the problem. I can offer this as a temporary workaround

(defun vetrm-send-plus ()
    (interactive)
    (vterm-send-string "+"))

Then you bind this to +. Similarly with *.

I will try emacs 28 to see if there's anything wrong with it.

[dangirsh]

Thanks!

Your fix works for me.

My system is XMonad running on Xubuntu 20.04 (though the same problem occured on 18.04). No desktop environment is running.

I'm pretty sure I would have noticed this problem sooner if XMonad was the culprit, so my guess is it's a new Emacs issue.

I updated to Emacs 28 and I found that + and * work (on my machine), so it's likely not a general problem with Emacs 28.

@jixiuf Yes, that was the issue.

I had accidentally bound the numeric plus to my keyboard instead of the normal plus. Hadn't realized there were two plusses!
