\begin{sidequest}[How the screenshots in this guide were made]
Every screenshot here is the real app, driven by \code{docs/guide/tools/screenshots.sh}: it starts throwaway
SSH, IRC, VNC and GitHub-ish servers, fills a demo data folder, and runs Nexus Terminal headless with
\code{--screenshot}, \code{--do} (run a palette command) and \code{--answer} (fill a password prompt; only accepted together with \code{--screenshot}). Change the app,
rerun the script, rebuild the guide.

\chapter{Glossary}\label{app:glossary}
\chapmeta{dip in}{Words you might trip over, in one line each}

\begin{multicols}{2}\small
\begin{description}[leftmargin=0pt, itemsep=5pt]
  \item[Agent] A background program holding your unlocked SSH keys, so you type the passphrase once.
  \item[Asciicast] The file format for terminal recordings. Plays in Nexus Terminal and \code{asciinema}.
  \item[Bastion / jump host] A server you go \emph{through} to reach the ones behind it.
  \item[Baud rate] How fast a serial line talks. Both ends must agree.
  \item[Broadcast] Typing into several sessions at once.
  \item[Certificate authority] A key that vouches for other keys, so servers signed by it are trusted without a prompt.
  \item[DTR / RTS] Serial control lines. Some boards use them for reset or flashing.
  \item[Fingerprint] A short summary of a server's host key, used to spot imposters.
  \item[Host key] A server's identity. Changes when it's rebuilt, or when someone's pretending.
  \item[Keychain] Your operating system's password store.
  \item[NLA] Network Level Authentication: Windows checks your password before building a desktop.
  \item[OSC 133] The escape codes a shell uses to mark its prompts, which powers shell integration.
  \item[Port forward] A tunnel carrying one TCP port through SSH.
  \item[Profile] A saved connection.
  \item[RAW TCP] A plain socket: bytes in, bytes out, no terminal rules.
  \item[RDP] Microsoft's Remote Desktop Protocol, for Windows (and xrdp) desktops.
  \item[SASL] How IRC networks log you in while you connect, instead of messaging NickServ afterwards.
  \item[SFTP] File transfer over SSH.
  \item[Snippet] A saved command, optionally with blanks to fill in.
  \item[TOTP] Time-based one-time passwords: the six digits from your authenticator app.
  \item[Trigger] A rule that watches output and reacts to a pattern.
  \item[Vault] Nexus Terminal's encrypted password store, for when there's no keychain.
  \item[VNC] A way of seeing and controlling another computer's desktop.
