The following happens on different Linuces:
When I’m in a virtual console, hold Alt and press ← or →, the virtual ttys cycle. This is really annoying as I’m using fish-shell which also uses this key combo. I could remap fish’s short cuts, but I don’t want to. Instead I want to disable the linux function or remap it.
How can I disable or change the tty-cycling-key-combo?

Method 1
Here’s a one-off fix:
sudo sh -c 'dumpkeys |grep -v cr_Console |loadkeys'
Method 2
I refactored Tobu’s answer to change only the absolutely necessary:
sudo sh -c 'dumpkeys -k|grep -v Incr_Console|grep -v Decr_Console|grep -v Last_Console|loadkeys'
NB: As said this is a one-off fix, and will probably be gone after a reboot.
Method 3
I had the problem sometimes with Ubuntu 18.04:
sudo kbd_mode -s
Did the job. (at least temporarily)
You can find a long bug report here on launchpad .
Method 4
You can use the loadkeys command to remap keys on the Linux console. The following lines define the key bindings to switch consoles (on a PC keyboard):
alt keycode 105 = Decr_Console alt keycode 106 = Incr_Console
Load your own keymap file that overrides these bindings with an escape sequence that fish recognizes. To make a key send an escape sequence, you need to bind it to a key name of the form FNUMBER and define a character sequence for FNUMBER.
alt keycode 105 = F105 alt keycode 106 = F106 string F105 = "3333[D" string F105 = "3333[C"
Different distributions (and sometimes different packages for console support) store the system boot-time keymap in different locations under /etc. Look for a file called *.kmap or *.kmap.gz or *.map or *.map.gz under /etc or consult your distribution’s manual. Some distributions store a the keymap’s name in /etc instead and put the actual keymap elsewhere; look for a keymap-related setting under /etc/sysconfig or other configuration directory.
You can either write your own keymap and use include "/path/to/foo.map" to reference the system keymap, or arrange to load your own keymap containing just the settings you want to change during the boot process.
Method 5
On my modern systemd system, I ran localectl set-keymap us and localectl set-x11-keymap us, which resolved this issue for me.
In general, the simplest way of setting keymaps on systemd systems is probably localectl. See the Arch Wiki for further details.
