Hi again, Thanks for your response.
If you do C-h f org-meta-return, do you see something like "This function has .. advice: .." towards the end of that *Help* buffer?
After investigation, the bug is in org-insert-heading in org 9.6 (Latest Doom - upgraded today - uses exactly version: (9.6-??-971eb68) The documentation says: "If point is in the middle of a line, split it and create a new headline with the text in the current line after point (see org-M-RET-may-split-line on how to modify this behavior). As a special case, on a headline, splitting can only happen on the title itself. E.g., this excludes breaking stars or tags. Whatever the value(s) I put in org-M-RET-may-split-line , org-insert-heading *always* creates a new line with a empty heading/item and leaves anything that was on the initial heading/item in-place. If someone can confirm this finding, I would be happy to create the corresponding bug report. Have a nice day -- Guillaume MULLER - PhD DataScientist Saint-Étienne
org-insert-heading is an interactive and byte-compiled function
defined in org.el.
Signature
(org-insert-heading &optional ARG INVISIBLE-OK TOP)
Documentation
Insert a new heading or an item with the same depth at point.
If point is at the beginning of a heading, insert a new heading
or a new headline above the current one. When at the beginning
of a regular line of text, turn it into a heading.
If point is in the middle of a line, split it and create a new
headline with the text in the current line after point (see
org-M-RET-may-split-line on how to modify this behavior). As
a special case, on a headline, splitting can only happen on the
title itself. E.g., this excludes breaking stars or tags.
With a C-u prefix, set org-insert-heading-respect-content to
a non-nil value for the duration of the command. This forces the
insertion of a heading after the current subtree, independently
on the location of point.
With a C-u C-u prefix, insert the heading at the end of the tree
above the current heading. For example, if point is within a
2nd-level heading, then it will insert a 2nd-level heading at
the end of the 1st-level parent subtree.
When INVISIBLE-OK is set, stop at invisible headlines when going
back. This is important for non-interactive uses of the
command.
When optional argument TOP is non-nil, insert a level 1 heading,
unconditionally.
Key Bindings
This command is not in any keymaps.
