How do I get back my greyed out cut and paste in WRITER ?
May be your document is openend Read only - check Edit -> Edit Mode
.
In some (not regular) cases LibreOffice denies to use the clipboard. Restart (of LO) often is the remedy.
Sometimes pasting by STRG+V can do, repeat it for some times and accidentally regular pasting works again. Don’t panic.
Cannot answer my question that is why I asked.
Any why do you post an answer to a question, which you cannot answer?
