Adding the useful alternative key binding of <kbd>CTRL-up</kbd> is tricky and determined by the terminals adherence to terminfo(5).
Conveniently FISH uses a command to capture keystrokes and advises you of the exact command to add for your specific terminal.
In your terminal, run `fish_key_reader` then punch the desired keystroke/s.
For example, in Gnome Terminal the output to <kbd>CTRL-upkey</kbd> is `bind \e\[1\;5A 'do something'`
So, adding this to the above sample, `bind \e\[1\;5A _atuin_search` will provide the additional search keybinding.
