Shift + [numeric keypad Enter] runs code as it was before cell edit

[ilze02]

There are two Enter buttons on my keyboard. The one that is on the main pad behaves as expected, but the one that is at the numeric keypad sometimes causes old code being run.

Steps:

1. create new blank notebook;
2. write:
   i = 9
   print(i)
3. press Shift+Enter
4. edit cell, replace 9 with 3
5. press Shift+Enter (the one at numeric keypad)

Expected output: 3
Actual output: 9

This does not happen, when using the other Enter key. This happens only if Shift+Enter is used right after edit (does not happen, if notebook is saved between edit and run or if you move cursor to another cell and back between edit and run).

Shift + numeric key pad enter doesn't submit for me (it enters a new line)? What OS are you running on?

And if you go back and use the regular enter, does it work again?

Thanks.

Windows 10.
Both Enters together with Shift for me runs the code in the cell.
"And if you go back and use the regular enter, does it work again?" <- yes. If i go back and use the "bad" Enter, it also works correctly.
The only time I see the unexpected behavior is when I run the cell with "bad" Enter right after editing the cell.

@greazer, more info needed?

Thanks for the information, please could you try updating to the latest version of the extension?

[ilze02]

Updated to latest version.
Now Shift + numpad Enter behaves as rchiodo explained: doesn't submit, enters a new line.

Better, but not ideal. Really used to JupyterLab behaviour (both Enters do the same thing). But If this is as designed, then I think we can close this issue.

[rchiodo]

Not by design, numpad enter should behave the same way.

Thanks for the feedback! However, we don't have plans on adding this functionality at this time. VS Code itself is investigating making notebooks a native experience in the editor. This particular problem will be solved by that effort.
