-Very useful progress.
-Keystroke sequences are now stored in an array of structs.
-This makes it VERY easy to see the various special flags
-in a keystroke sequence
-(e.g. Esc, Ctrl, Alt and so on..... ).
+Almost there!
+The code now "pretty much" works as expected.
+( However, pressing Enter exits the program rather
+than storing the existing command-line and "staying
+in the program". I hope to fix this soon. )
+
+You can edit a command-line (using backspace).
+You can move around with left and right-arrow
+keys.
+Command-history can be recalled from a file with
+the up-arrow key, and you can scroll up and down
+through the command-history.
+
+*** CAUTION! *** - There is, however, an occasional
+problem with "stack-smashing".
