macOS keyboard shortcut for correcting misspelled words?
You can't correct them in a single click, but you can make it start to go though them in bulk, correcting each on the way.
 Cmd ⌘   :  [which on a UK keyboard is actually  Cmd ⌘   Shift ⇧   ;  ] will pop up the Spelling &amp; Grammar checker, allowing you to select each error in turn &amp; correct it [or ignore, learn etc]

Alternatively ... Edit Menu &gt; Spelling and Grammar &gt; Show Spelling and Grammar
