Is there a shortkey to use "Always correct to"? It would saved have millions of hours.

Usually, people do a lot of word typing mistake, and 95% of the time, the mistaken words is on the top of the list of “Always autocorrect to”. For me, I waste my time using putting simple words mistakes into “always autocorrect to”.
If u have used Android, the Google do it for u. Save a lot of time and energy to re-correcting simple words mistake.

I wish, there was some options or any such approach/mechanism for this. So then we can enable it. And enjoy LibreOffice. Kind of like an AI understanding what is that supposed to mean.

Until then, another feature request.
(I think some things should not need to be ‘feature requested’, it should be, be there by default.)

We still lack Grammarly. Life is tough here in Linux. Because obviously, Windows user would prefer MS word.
We need a modern solution to a modern problem. LibreOffice should advance faster.

Until then, another feature request
