[amtoine]

that is a proposition, e.g. instead of having

Error:
  × User choose to exit...
    ╭─[scripts/prompt.nu:27:1]
 27 │     if ($choice | is-empty) {
 28 │         error make (context user_choose_to_exit)
    ·         ─────┬────
    ·              ╰── User choose to exit...
 29 │     }
    ╰────

when pressing <C-c> inside the selection of repo goto we could have a simpler

User choose to exit...
