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? Regards -- Assoc.
