 To open a spell check window press :kbd:`F2` or :menuselection:`Edit --> Check Spelling`. If the spell check does not find a what you typed that spellcheck does not recognize will be shown from :guilabel:`Unknown word` followed by what is typed. If this is correct press the :guilabel:`Add To Dictionary` button to never have to deal with spellcheck marking this wrong again. To see what is wanted as a replacement for a typo see :guilabel:`Replace with` for the first suggestion and beneath this is a list of things to replace with. To choose a different suggestion left click on the suggestion to switch to it. To correct this typo just once press the :guilabel:`Correct Once` button. To correct this spell check every single time in your file press the :guilabel:`Correct All` button. To not change what you have typed in just this case press the :guilabel:`Ignore Once` button. To ignore what you have typed press in the entire file press the  :guilabel:`Ignore All` button. If you do not have a spelling error on the bottom will appear a red bar saying :guilabel:`No misspelling from text cursor`.
