LSE for Pascal: Guess My Number tutorial

LSE for Pascal Loading... Screen Source

The keys are the same as in the terminal version; the key bar at the bottom of the screen lists them, and F1 shows the keypad. You can also click (or tap) a key in the key bar to press it.

The F-keys on a Mac keyboard control the Mac (F4 opens Launchpad or Spotlight). Hold fn for the F-key: fn F4 is Hint, fn F6 lists the tutorial's steps. Or press esc and then the digit (esc 4 is F4, esc 6 is F6), or ⌥ option with the digit (⌥4, ⌥6). esc 0 or ⌥0 is F10.
^ in the key bar means ⌃ control, not ⌘ command: ^L is ⌃L and ^Q is ⌃Q (⌘Q quits the browser). ⌥W, ⌥N and ⌥Q do the same as ⌃W (other window), ⌃N (next placeholder) and ⌃Q (quit). ⌃P opens the LSE> command line for everything else.
Your files stay in this browser, so the tutorial resumes where you left off. Start over erases them.

If the browser takes an F-key for itself, press Esc and then the digit: Esc 5 is F5, Esc 6 is F6 (the tutorial's steps), Esc 0 is F10.
Browsers keep Ctrl-W, Ctrl-N and (in some) Ctrl-Q. Use Alt-W (other window), Alt-N (next placeholder) and Alt-Q (quit) instead. Ctrl-P opens the LSE> command line for everything else.
