Why A is creating a new cell below and B a new one above?

JupyterLab

Grettings, everyone! I’m wondering why this is happening. I’ts doing the reverse of what it should be doing.

When i click on A is creating a new cell below and when i click on B is creating one above.

Thanks for your attention.

I’m trying in fresh session of JupyterLab Version 4.2.5 right now and it is as expected. (Same with 4.3.1.)
What does it say it should be for you in Settings > Settings Editor > Keyboard Shortcuts for the ‘Insert Cell Above’ and ‘Insert Cell Below’ settings? You didn’t change the default?

v4.2.5 Pertinent Keyboard Shortcuts (believed to be defaults):

JLv4.2.5_insert_options
JLv4.2.5_insert_options1071×142 8.62 KB

v4.3.1 Pertinent Keyboard Shortcuts (believed to be defaults; try here):
JLv4.3.1_insert_options
JLv4.3.1_insert_options1068×136 6.84 KB

To get more information, it would help if you mention what version you are concerned about?

You may want to look at the recent discussion Commands to insert cell below/above have unexpected effects on the active cell · Issue #17026 · jupyterlab/jupyterlab · GitHub, which seems to be related to this.

I believe that it is “B” for “before,”
and “A” for “after.”

Hope this helps.
