Title: keyboard setting interferes with all other shortcuts Status in unity-control-center package in Ubuntu: New Bug description: Security-related part of the issue: After going into 'system settings > keyboard > shortcuts > typing', and changing the 'compose key' setting from 'Disabled' to 'Left Control', it messes up ALL keyboard shortcuts in ALL windows. This means that I cannot terminate a command in terminal (because the only way to terminate something is to hit control+c). This is a security risk because if I need something to terminate, I can't terminate it. I also cannot lock this computer using control + alt + l. the general issue: I cannot use this operating system without a mouse, after doing thing change in settings. All operating systems should be usable by keyboard alone. After changing this setting, I should be able to use other keyboard shortcuts (like SUPER (dash) and alt + tab (switch windows), especially since they're not associated with the control key). The compose key doesn't even work, with the setting 'left control'. The user SHOULD have the liberty to choose whatever key combination configuration they please (instead of being confined to the limited drop-down options). If you can't get the key combination thing to work, you should try adding an option for something like 'left control + left shift' for the compose key combination. Also, I keep my keyboard scroll lock turned on (so my keyboard will light up), but after changing this setting it turned off, and I could not turn it back on by pressing the scroll lock button (I do this by typing "xmodmap -e 'add mod3 = Scroll_Lock'" in terminal every time I restart my computer and login, then pressing the scroll lock key on my keyboard). information: results from typing 'lsb_release -rd': Description: Ubuntu 16.04.1 LTS Release: 16.04 results from typing 'apt-cache policy unity-control-center': unity-control-center: Installed: 15.04.0+16.04.20160705-0ubuntu1 Candidate: 15.04.0+16.04.20160705-0ubuntu1 Version table: *** 15.04.0+16.04.20160705-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 100 /var/lib/dpkg/status 15.04.0+16.04.20160413-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages results from typing 'sudo dmidecode -t 2': # dmidecode 3.0 Getting SMBIOS data from sysfs.
