Ctrl+C doesn't work in Guake Terminal

The problem is, that ctrl+c is also the shortcut to copy something. So you have to bind the SIGKILL-shortcut to something else that the shortcut in the terminal works. For example withAutoKey

There was a ticket at guake.org three years ago which answer explains it well:

Ctrl+C is historical key combination for killing foreground process in unix terminals. Under the hood, it sends SIGINT signal to the foreground process, and default effect of that is termination of the process. However, any application is able to catch and block that signal, ignoring the request for termination. Several dozens of other signals exist with their specific functions, SIGSTOP for example stopping the process (with possibility to resume later), SIGTERM unconditionally terminating the process, etc.

But, Ctrl+C is also widely known shortcut to "copying" operation, ubiquitously used in MS Windows applications. Modern Linux desktop environments emulate the behavior to cause less confusion to migrated users, but the native selection system of X windows uses middle mouse button for "copypasting" rather then hotkeys. Just select source text and click with the third button in the destination area. Selected text will be pasted.

As Guake uses VTE component provided with GNOME (which is the one responsible for handling ^C, the terminal killing one), I'm afraid, we cannot help the conflict. Bind "copypasting" Ctrl+C to something other (I have it binded to Ctrl+Shift+C) and get used to it; or try to accommodate yourself with the middle click way - it's pretty convenient indeed. And yeah, patches are as always welcome - so you may try to fix everything yourself (though this is not a bug, this is a conflict: nothing to fix, rather to find not-very-harmful workaround).

For linux, not Windows, CTRL+SHIFT+C and CTRL+SHIFT+V are for copy and paste respectively as CTRL+C is always kill the running command in the terminal as far as I have ever seen as this is essential. It appears the user is trying to kill the running code not copy and paste it appears the fact that CTRL+SHIFT+C is not working is subsequent to the issue. – mchid – 2016-08-31T11:27:26.807

I forgot I remapped my CTRL+SHIFT+C (and CTRL+SHIFT+V) to CTRL+C/V under the Guake Preferences. And of course why I'm here. Not sure why OP is having issues, however, my issue is was self induced and now solved. – Natetronn – 2019-03-05T21:08:04.960

Ctrl+C does not send SIGKILL, it sends SIGINT. – Josh Correia – 2020-01-31T17:28:18.010

1OK, but in my case ctrl+C doesn't copy anything and is not bind to anything. – eneepo – 2013-10-09T08:44:22.020

I would recommend you to try to remap the sigkill-command(ctrl+c in terminal) to another shortcut and than try it again. – Christian – 2013-10-09T08:50:59.150

I tried to change it by stty intr \^k not only it didn't work, I understood that non of my shortcuts work! – eneepo – 2013-10-09T09:07:20.500

have you tried to re-install guake? – Rudolph – 2013-10-09T09:14:50.820

Yeah, but it didn't worked – eneepo – 2013-10-09T09:15:25.993

Do any shortcuts work outside of the terminal? – Christian – 2013-10-09T09:20:39.713

Yes, they do. All of my gnome and gnome-terminal shortcuts work perfectly. – eneepo – 2013-10-09T09:24:24.307
