The Spell Check panel displays a list of spelling errors in variable names. To open it use the Open Spell Check Panel from the Window Menu.
The panel will show a list of variable names that have spelling errors in them. Click on a variable in the list to navigate to that variable and open its name for editing. Once the name is open you can right-click or Ctrl+Click (⌘+Click on Mac) to open the Context Menu and use the spell check options there to select an alternative, ignore the word or add it to the dictionary.
When you change the spelling of the word or choose to ignore it an add it to the dictionary it will be removed from the list. Ignoring and adding to the dictionary may also remove other variables from the list. When there are not more errors detected the list will be empty.
Note Words that you add to the dictionary or are stored in your preferences. This means you may see different words highlighted on a different computer for other models.
Note Adding words to the dictionary or choosing to ignore them is not part of the undo/redo system. Once added/ignored they remain added/ignored.
