Shift+Up does not return to beginning of entry

[mahi2003]

Down and Up are the buttons as labeled on the stock DM42. With the db48/50x overlay they are Left and Right.

In entry mode you can press Shift+Down to move the cursor to the next line or the last position in the line if no lines follow. Shift+Up moves the cursor up to the previous line, but if you are on the first (or only) line, Shift+Up does not seem to have any effect. I'd expect it to set the cursor to the first position.

"Hello world"

Set cursor to anywhere but first or last character. Press Shift+Down and the cursor moves to the last position. Now press Shift+Up and nothing happens.

"Hello
world"

With the cursor at the first position, press Shift+Down. The cursor moves to the second line. Press Shift+Down again and the cursor moves to the end of the second line. Press the Up arrow once (*). Now press Shift+Up to return to the first line. However, pressing Shift+Up once more does not return us to the beginning of the first line.

(*) If you don't do this, the cursor moves directly to the first position of the first line after pressing Shift+Up. It seems that pressing Shift+Up/Down does not update the last column the cursor is on.

By the way, sometimes when writing a program or longer entry, I might accidentally press Shift+Shift+Up instead of Shift+Up to move up a line. The result is that I get a previous entry from history that overwrites the current entry (in other words my entire entry is lost). This can be quite frustrating...

I'm not sure to file this as a bug because technically it isn't - the overlay clearly states Shift+Shift+Up is history, but it's an easy mistake to make because you need Shift and Shift+Shift so often. Perhaps history should work only with the cursor at the first position? Or allow you to exit history without losing the current entry?

Thanks a lot for the bug report regarding cursor movement. I will fix it right away.

The good news is that the entry is not lost. Simply use Shift-Shift-Up again to go back further in the editing history. It's at most 8 deep, so in the worst case, you have to go back 8 levels.

I'll try to think of a convenient way to go through history without having to use double-shift every time. Maybe HIST could be a mode where up and down go through history, and you exit it with ENTER?

Confirmed fixed in 0.7.8!

I had not noticed that. Thanks!

The history feature confuses me. Perhaps I don't fully understand its purpose/working.

1 ENTER 2 ENTER 3 ENTER 4 ENTER 5 ENTER 6 ENTER 7 ENTER 8 ENTER

HIST (Shift+Shift+Up) → 8 HIST → 7 HIST → 6 EXIT HIST → 6: Why doesn't it start from the beginning (8) again? HIST → 8 HIST → 7 HIST → 1: Huh? HIST → 5 HIST → 4 HIST → 3 HIST → 2 HIST → 6: Err...
