M-s <left> is undefined.

M-s <left> is undefined.

[Hongyi Zhao]

Based on the document located at
<https://orgmode.org/manual/Built_002din-Table-Editor.html>, I try the
following instruction:

M-S-LEFT (org-table-delete-column)

Kill the current column.


But the keystroke combination doesn't work as expected, instead it
triggers the following info in the bottom minibuffer:

M-s <left> is undefined.

The environment is Ubuntu 20.10 with the self compiled latest git
master version of emacs and orgmode.

Any hints for this problem?

Which keys, exactly, are you pressing?

M-S-Left in Emacs Key Notation (
https://www.emacswiki.org/emacs/EmacsKeyNotation) refers to
Meta-Shift-Left, which in my testing works as expected, but the message you
see, as posted, corresponds to what happens when you press Meta-s (the
letter S) followed by "Left".

Really, it's my misapprehension on the key stroking sequence
corresponding to the EmacsKeyNotation M-S-LEFT. In fact, I've tried
the following keys pressing orders:

Alt + s + left-arrow
Alt + (left|right)-shift + s + left-arrow

Thanks, the following key stroking order does the trick:

Alt + shift + left-arrow
