Arch Linux

So this is completely on me:

I installed Arch
I installed the plasma desktop without any additional programs
I installed sddm and told it to launch plasma desktop
I rebooted

And it did what I told it to do perfectly:

I'm now within plasma desktop.
I have no terminal emulator installed, so no way of accessing a command line from within the GUI.
Whenever I reboot, I get put back into plasma desktop.
I tried to switch to a different tty with Ctrl+Alt+F-keys but that key combo seems to be used for additional desktop sessions instead (shows me the sddm login again).
I tried creating a shell script that launches pacman and installs a terminal, but I can't, since I don't have a text editor installed.

Help!

[Edit: Solved. I was able to go to a different tty after disabling function keys]
