If your Mac has a Touch Bar, you can set an option to show typing suggestions in the Touch Bar. While typing, you can display a list of suggested words by pressing F5 (you may need to also press the Fn key, depending on your Mac model). If an app’s Edit menu doesn’t include a spelling or grammar command, check its settings or menus to see if it has its own spell checker. To turn off autocorrection for a specific app, open the app, then choose Edit > Spelling and Grammar > Correct Spelling Automatically (it’s off when a checkmark isn’t shown). You can also Control-click the word to show your spelling, then choose it. To revert to your original spelling, put the insertion point after the word to show your original spelling, then choose your spelling. Undo autocorrections: An automatically corrected word is briefly underlined in blue. Ignore suggestions: Press Esc, then continue typing. If two or more suggestions are shown, choose one. Note: To have the first word of a sentence and proper nouns (such as California or Tim) automatically capitalized as you type, turn on “Capitalize words automatically.”Īs misspelled words are detected, do one of the following:Īccept suggestions: If there’s only one suggestion, just keep typing to have the word autocorrected.

Install and reinstall apps from the App Store.FAROO just uses a limited concept of a bad hash function. This is still an edit-distance limited search, but it's very fast because the pre-calculation step works like my "bad hash functions" idea. This is important for fuzzy/similarity search beyond spelling correction where no empirical knowledge exists. Update: I've since found one algorithm description that's similar to this, the FAROO Distributed Search. A 5 letter word has about 3 million possible spelling errors within a maximum edit distance of 3, but with SymSpell you need to pre-calculate & store only 25 deletes. With the pre-computed approach, you get maybe a couple hundred candidates, and you know that they're all correctly spelled, so you can skip straight to ranking. With approaches that try to generate alternate spellings (as in the Peter Norvig article), you can get (tens of) thousands of candidates that you first have to filter against the dictionary. Remember the collision lists contain only words that are in the dictionary. So now you look up misspellings in each of the auxiliary indexes and concatenate the collision lists before ranking. Please click File tab in Word 20 (or click the Office. In practice, I found simplistic pronunciation ones to go a long way and essentially obsolete some of the ones designed to find trivial typos. The automatic Spell Check function might be disabled sometimes and users could reactivate it. In practice, you'll need a few auxiliary indexes with other hash functions to handle other types of errors, like transposed letters, single/double letter, and even a simplistic Soundex-like one to catch phonetic misspellings. Ta da: You have a suggestion list! All you have to do is rank the words on it. Now, when you find a misspelled word, you look up the collision lists for the bucket that the misspelling maps to in the auxiliary indexes. The buckets in this table will have longish collision lists because the hash function is "bad", but those collision lists are essentially pre-computed suggestions. Insert all of your dictionary words into an auxiliary index (hash table) using this special hash function. The "normalized" word is then hashed with a typical hash function. In this example, the normalizing function might drop all the vowels, so definite becomes dfnt. An easy way to do that is to first "normalize" the input word and then put the normalized result through a regular hash function. Microsoft Word 365 subscription is required. As an alternative, you can install the add-in directly from Microsoft AppSource. Click it to activate LanguageTool’s advanced grammar and style correction. So you design a hash function that treats all vowels as the same letter. After installing the add-in a check text button will appear in the Home tab of your Word document. The idea is to look at the types of spelling errors people make, and to design hash functions that would assign an incorrect spelling to the same bucket as its correct spelling.įor example, a common mistake is to use the wrong vowel, like definate instead of definite. An approach for generating suggestions that I've used successfully but never seen described anywhere is to pre-compute suggestions (when building the dictionary) by using "bad" hash functions.
