I use irsii in terminal, and I would like to use Alt-1, ..., Alt-9 to switch between irssi windows, but these keybindings are already taken from terminal to switch between terminal tabs.
I read this useful answer, and I explored the settings in dconf-editor, but I didn't find anything useful.
Thanks to the answer of @"Alex Mitchell", I realized that the alt_changes_tab setting is responsible for the behavior I would like to modify, and I realized that this setting can be accessed and changed through dconf-editor, so I eventually solved my problem.
Edit I mean, changed in the sense that the Alt+num keybindings can be completely disabled, not configured, but this is enough for me.
Edit2 To answer to the comment:
install the package dconf-editor, I did it from command line
sudo apt-get install dconf-editor
launch the application, it is called Editor dconf,
Unfortunately the terminal shortcuts are hardcoded. I'm not sure if there's plans to make them configurable. To solve your problem, I see two possible solutions:
Modify the source code and compile locally. I see some mention of alt keys here https://github.com/elementary/terminal/blob/master/src/PantheonTerminalWindow.vala#L410. It might be as simple as removing the cases case Gdk.Key.@1: to case Gdk.Key.@9: from the switch statement. There's also instructions on how to compile here https://github.com/elementary/terminal/
Use a different terminal emulator like xterm or gnome-terminal
As you haven't specified which terminal you would like to use, the answer was simply:
sudo apt install gnome-terminal
From here you can set the shortcuts the through the normal preferences.
