Thank you, Ihor, for your input. You are right on these points.
1. The narrow/widen labels can be confused with buffer narrowing, so I
changed them to "decrease width" / "increase width".
2. "quick help" and "quit" were too vague in this context. I changed
them to "toggle help" and "quit column view", respectively.
3. I also changed the `org-columns-redo' label from "redo" to
"refresh", matching the menu wording and the `g' binding shown by
quick-help.
I also added a guard for older supported Emacs versions. Org currently
declares support for Emacs 28.2 and newer, while `help-quick' was added
in Emacs 29. On Emacs 28, the command now reports a clear user error
instead of failing with `void-function'.
The final quick-help popup now looks like this:
Value Column Move row/column
View Misc.
e edit M-S-<right> add M-<up> row up
c contents g refresh
a allowed M-S-<left> delete M-<down> row down
o overview ? toggle help
S-<right> next < decrease width M-<left> column
left v show value q quit column view
S-<left> previous > increase width M-<right> column
right C-c C-o open link
C-c C-c toggle checkbox s attributes
C-c C-t TODO
I merged the change to main and added an entry to ORG-NEWS.
Best,
