   As I type (e. g. in this compose window in Thunderbird, or in a webform   
   - but not, I've just checked, in Notepad!), words mis-spelt are   
   underlined in wiggly red; I presume this is something built-in to   
   Windows 10.   
      
   Right-clicking on such a word brings up a menu, including suggestions   
   and also Add To Dictionary.   
      
   I've always been wary of such, in case I add something that was just a   
   genuine mistype, as I don't know where the dictionary is nor how to edit   
   it. Anyone know?   
      
   (I've just discovered that right-clicking on the word after adding - as   
   I just did with "webform" above - provides an Undo Add To Dictionary   
   option. But of course that will only work straight after the adding, not   
   much later, as for example might happen when you added a genuine   
   mis-spelling you thought was right and only much later discover wasn't.)
