I'm a creature of habit and I'm used to correcting my misspelled words by recognizing the red underlined word, highlighting it and seeing the suggested words to replace.

See below screen shot.  I spelled "spelling" incorrectly on purpose, highlighted the word to get the correct spelling and clicked on it.  This screen shot is from another website that hasn't been updated yet.

Since this new update, I can not highlight, right click, and retrieve the correct word. 

If I have a misspelled word, and go to highlight or even if it's not a misspelled word and highlight, I get the below link button when I right click.  I've looked in the TinyMCE editor settings.

Since I already figured out this new editor wants me to use command keys for the copy paste, I thought that maybe with correcting a misspelled word, this new update would require the same use in a command.

I tried:  press Ctrl+Alt+X, but that didn't work either.

What could I be doing wrong?🤓

Thank you for visuals and tutorial.  I use Mozilla Firefox and I have all of those settings correct.  I had tested on Chrome yesterday and had the same results.  I just checked my Chrome settings and they are correct, set to check spelling as you type. 

After taking a look at your link, it would seem that is what is needed to customize.  I'll check on my Mac and see what results I'm getting first.

I'm still looking into this though, thank you for your suggestions.

Thank you for your video.🌹

I went to my Mac to reproduce your screen shots in Chrome.  Mozilla Firefox is structured a bit different for spell check, but I believe I have both adjusted right.  I will play with it some more in the morning.
