History keyboard traveling is inconsistent

[mkrl]

Describe the bug

Sometimes you can slip into the "undefined" territory when searching the command history with a keyboard. Also, the "down" history navigation would be nice to have

Steps to reproduce

Steps to reproduce the behavior:

1. Open up the terminal
2. Without typing any commands, press "up"
3. See "undefined" show up in the terminal

Also, when navigating with the "down" arrow:

1. Open up the terminal
2. Type several commands
3. Travel up the history and then down. It only works after pressing the "down" several times and is not consistent.

Expected behavior

Navigating the history when the history is empty should not print anything in the terminal.
Navigating down should be instant and should seamlessly scroll the history down.
