Help may teach by showing

[quozl]

We have a Help button which shows a few commands, added in 2012 by @godiard and @aguzubiaga.

We also have Activity Help via the Frame or alt-shift-h, which shows terminal.rst.

We might extend this into a scripted demonstration;

• a popup help window, with a Vte, explanatory text, reload, forward and backward buttons,
• a series of topics, starting with basics,
• some script(1) files with timings, along with scriptreplay(1) output to the Vte, see also asciinema for a more modern alternative,

Topics might include;

• recognising the prompt and the text cursor,
• typing a command, and seeing it echo, e.g. df -h ., and recognising the output,
• fundamentals of a REPL; that it waits forever, it does exactly what you ask, it is repeatable,
• making mistakes; shell command recall and editing, accidental destruction,
• copying and pasting commands,
• scrolling through long output (ls -laR); returning to the prompt,
• typical user-level tasks; filesystem tools, starting graphical programs, using the Python REPL,
• typical sugar tasks; gsettings, cloning an activity,
• typical system-level tasks; investigating a system, installing software; with context recognition for Fedora or Debian systems,
• finding commands for a task; other documentation,

Implode activity has this kind of embedded help. Please try it out.
