+## How do I remove the default up arrow binding?
+
+Open your shell config file, find the line containing `atuin init`.
+
+Add `--disable-up-arrow`
+
+EG:
+
+```
+eval "$(atuin init zsh --disable-up-arrow)"
+```
+
+See [key binding](https://docs.atuin.sh/configuration/key-binding/) for more
+
+## How do I edit a command instead of running it immediately?
+
+Press tab! By default, enter will execute a command, and tab will insert it ready for editing.
+
+You can make `enter` edit a command by putting `enter_accept = false` into your config file (~/.config/atuin/config.toml)
