You can have Keynote check spelling while you type and correct mistakes automatically. You can also have Keynote check grammar and add terms to the dictionary so they’re not marked as misspellings.
If you want to check spelling in a different language, first change the language of the dictionary.
While you’re working in a presentation, do any of the following:
Check spelling: Press Command-semicolon (;) on the keyboard, or choose Edit > Spelling and Grammar > Check Document Now (from the Edit menu at the top of your screen). The first error is highlighted. To show the next error, press Command-semicolon again. To see suggested spellings for a word, Control-click it, then click the correct spelling.
Check grammar: Choose Edit > Spelling and Grammar > Check Grammar With Spelling (a checkmark shows it’s on). Grammar errors are underlined in green. Move the pointer over an underlined word to see a description of the problem.
Ignore a misspelling: Control-click the word, then choose Ignore Spelling. The word is ignored if it occurs again in the presentation (it will be marked in other presentations).
Add or remove a word from the spelling dictionary: Control-click the word, then choose Learn Spelling. The word is added to the dictionary so it won’t be marked in the future. To remove it, choose Unlearn Spelling.
When your spelling is checked automatically, misspelled words are underlined in red, and suggested corrections are shown.
If you don’t see autocorrect suggestions, make sure autocorrection is turned on. Choose Edit > Spelling and Grammar > Correct Spelling Automatically (it’s on when there’s a checkmark next to it).
Do any of the following:
Accept suggestions: If there’s only one suggestion, just keep typing to have the word autocorrected. If two or more suggestions are shown, choose one.
Ignore suggestions: Press the Escape key, then continue typing.
Undo autocorrections: An automatically corrected word is briefly underlined in blue. To revert to your original spelling, put the insertion point after the word to show your original spelling, then choose your spelling. You can also Control-click the word to show your spelling, then choose it.
For Keynote only: Choose Edit > Spelling and Grammar > Correct Spelling Automatically (it’s off when there’s no checkmark).
For all apps: Choose Apple menu > System Preferences, click Keyboard, click Text, then deselect the “Correct spelling automatically” checkbox. The Apple menu is in the top-left corner of your screen.
Do one of the following:
Add a word to the spelling dictionary: Control-click the word, then choose Learn Spelling in the shortcut menu.
Remove a word from the spelling dictionary: Control-click the word, then choose Unlearn Spelling in the shortcut menu.
You can open the Spelling and Grammar window to manage spelling and grammar in your presentation, and to check just a portion of your presentation.
Choose Edit > Spelling and Grammar > Show Spelling and Grammar (from the Edit menu at the top of your screen).
To choose just a portion of your presentation, first select the text you want to check.
To learn about finding and replacing text, see Find and replace text.
In System Preferences, you can set up your Mac to automatically check spelling for different languages.
Open System Preferences (from the Apple menu at the top-left corner of your screen).

If you have a dictionary file you want to use, copy it to the Spelling folder in your Library folder.
Click Done.
