Currently, there is no Shortkey for "Add to Dictionary" and no way to assign a Shorkey.

There are million new words generating day-by-day in each country. Different short form words.
And writing all that in an informal letter, and that Red color showing it up is really annoying.
Even the genuine formal words are not recognized by Libre Dictionary.

I don’t blame Libre for that. There are many such words.

My point is There gotta to be a way to assign Shortkey.

Right now, we have to right click and choose the option “Add to Dictionary” and that is very time consuming and frustrating.
(as always, love u guys).
