When I'm pressing the function keys, for example F12, I get a tilde symbol on my cursor position (~ sign). How can I turn this of ? This issue affects both shells, Bash and the Zsh.
What dotfiles should I paste ?

On bash from version 4.1, you can stop that from happening by sticking this into ~/.inputrc:
"\e[": skip-csi-sequence
That will make it ignore any keycode that isn't bound to anything else.
You can assign something to each of those keys. You can also assign a null string.
To find out the sequence emitted by each key, press Ctrl-v then the function key. On my system, for F12, I see ^[[24~. The "^[" represents Escape which will be represented by \e in the lines below.
In Bash, in your ~/.inputrc file, add lines like this:
"\e[24~": ""
or, if you want to make it output something:
"\e[24~": "Super User"
which will make the corresponding key do nothing.
In Z shell, you can add bindkey commands to your ~/.zshrc file like this:
bindkey -s "\e[24~" ""
or, if you want to make it output something:
bindkey -s "\e[24~" "Super User"

I believe the trailing ~ is being inserted by your shell, after the ctrl-v sequence executes, and will therefore not register correctly with keybind -- "\e[24~" should read "\e[24" – Adam Tolley Feb 8 '19 at 21:34

@AdamTolley: That is incorrect. Where would the shell get the idea that it should output a tilde? Can you show any evidence that your assertion is true? As counter evidence, I tried the sequence Ctrl-V F12 in: Bash, dash, ksh, zsh shells and in Gnome, xterm and terminator terminals under Ubuntu 18.04 and in all cases the tilde was output. It even worked similarly on a MacBook Pro in Bash in Terminal using Ctrl-V Fn-F6 (F12 changes to the widget screen). – Dennis Williamson Feb 8 '19 at 22:13
