Spell checking

I have been going through my 32-bit applications to see what I can dispense with when I eventually move on from Mojave. I have installed a couple of indispensable ones on a Mojave virtual machine in Parallels, but one application for which this won’t work is Spell Catcher. So my question is: are there any viable alternatives to Spell Catcher? Or do you just right-click on words marked as misspelt by the system spell checker to correct them? Having used Spell Catcher since 2004 and become accustomed to its popup window with numbered suggestions and other shortcuts, this would seem like an extremely backward step, as well as being inefficient. Or are there some tricks to spell checking that I aren’t aware of?
