To fix an error, call Context Menu for the misspelled word and choose the desired item from the Spell Checker submenu.
There are two ways to enable Spell Checker.
Open the Spell Checker options page and check the Enabled checkbox.
Click the Spell Checker button on the DXCore Visualize toolbar.
You can customize Spell Checker options via the Spell Checker options page.
