The course names keys the way the Einstein does: ENTER, DELETE, ESC, BREAK, GRPH, F0, CONTROL. Where that key is depends on what you are sitting at.
Press the key with that name on it. CONTROL and SHIFT are held down while you press the other key.
MAME lays the Einstein's keys over yours by position, so the key in the same place on your keyboard is the Einstein's key, whatever your keycap says.
| Einstein | In MAME |
|---|---|
| ENTER | Return |
| DELETE | Backspace |
| CONTROL | Ctrl (the left one) |
| ESC, TAB, SHIFT, CAPS LOCK | the key of the same name |
| The arrow keys | the arrow keys |
| BREAK | left Option (left Alt) - but it does nothing under the emulator |
| GRPH | F8 |
| F0 to F7 | F1 to F8 |
MAME has keys of its own - Escape to quit, F3 to reset - and starts with them switched off, so that those keys reach the Einstein. Forward delete (Fn and Backspace on a Mac laptop) switches them on and off. If Escape ever closes MAME, that is what has happened.

|---|---|
| DELETE | Rub out the character before the cursor |
| CTRL-S | Cursor one character left |
| CTRL-D | Cursor one character right |
| CTRL-X | Cursor down a line |
| ENTER | End the line; with auto-indent on, the next starts under the one before |
| CTRL-Q CTRL-I | Auto-indent off (Indent leaves the status line) |
| CTRL-K CTRL-D | Leave the editor, keeping your text |
TAB moves the cursor right and SHIFT-TAB left: on the Einstein they send the same codes as CTRL-D and CTRL-H, and CTRL-H moves left just as CTRL-S does. The arrow keys do not move the cursor; they type [ ] ^. DOWN does nothing visible.
