(insert "Insert a link. Use TAB to complete link prefixes, then RET for type-specific completion support\n") This causes a stretch in the message buffer, which sometimes is being a little bit annoying, I'm advising org-link-insert personally because of it. Maybe merging it into one line: (insert "Insert a link. Use TAB to complete link prefixes, then RET for type-specific completion support\n") Will make it better. -- Regards, Salih
