Configure spell check

The spell checker options (Advanced -> Configuration -> Spell Checker) allow selection of the main spelling dictionaries to be used by UltraEdit as well as some other options. You may select any of the languages shown, or if preferred may select none of the languages in which case UltraEdit will use only the user dictionary.

UltraEdit incorporates the Aspell spelling checker. The spelling checker is invoked from the Edit Menu and will check only selected text (if there is a selection) or the complete file if no text is selected.

Spell Checker

Spell Checker Dictionary Options

You can configure the spell checker’s dictionary options in Advanced -> Configuration -> Spell Checker -> Dictionary.

Aspell is installed along with UltraEdit and UEStudio. By default the executable for Aspell is located in the \Aspell\bin\ subdirectory below the installation directory.

Adding/Removing Words

You can add and remove words as desired. To add a word, first select a dictionary in the Dictionary pane. Next, type a word into the “Added Words” field and press Add. Your word has now been added to the selected dictionary.

To remove a word, select it and press the Remove button.

Spell Checker Filter Options

You may access the filter options under Advanced -> Configuration -> Spell Checker -> Filters. Setting a filter will cause UltraEdit’s spell checker to ignore certain items in documents spell-checked by Aspell. For instance, if you set the filter to “HTML”, the spell-checker would ignore html-specific tags such as “div”, “src”, and “href”.

If the Use Filters checkbox is selected the following options are available. (Only one filter may be used at a time.)

Automatic Detection

Selecting this option will result in the spell checker automatically detecting if a file is an HTML, Tex, or other file (as listed in the following selection options) and applying the appropriate filter.


The email filter skips over quoted text. This filter however currently does not support skipping over headers.


The HTML is similar to the SGML Filter, but specialized for HTML. By default, ‘script’ and ‘style’ are members of the skip list in HTML mode.


The SGML filter allows you to spell check SGML, HTML, XHTML, and XML files. In most cases everything within a tag, for instance “,” will be skipped by the spell checker. The SGML/HTML/XML that Aspell supports is a slight superset of most DTDs (Document Type Definitions) and can spell check the often non-conforming HTML found on the web.


The URL filter will cause the spell checker to skip over URLs, host names, and email addresses.


The Nroff filter allows you to check the spelling of Nroff documents. This filter mode skips following nroff language elements:

  • Comments
  • Requests
  • Names of nroff registers (both traditional two-letter names and GNU nroff long names)
  • Arguments to the following requests: ds, de, nr, do, so.
  • Arguments to font switch (\f) and size switch (\s) escapes
  • Arguments to extended charset escape in both traditional (\() and extended (\[comp1 comp2 …]) form.


The Tex filter will cause the spell checker to skip over TeX commands and parameters and/or options to certain commands. It also skips over TeX comments by default.


The C/C++ filter will cause the spell checker to skip over the spelling of text in strings or comments. This filter mode skips checking for spelling errors in source code.

Spell Checker Ignore Options

Ignore options for the spell checker are located under Advanced -> Configuration -> Spell Checker -> Ignore Options.

Ignore Case

Selecting this option will cause the spell checker to check all words against the set dictionary regardless of the word’s case.

Ignore Accent

Selecting this option will cause the spell checker to ignore accented letters.

Ignore All-Caps Words

Selecting this option will cause the spell checker to ignore words in all caps.

Ignore Capitalized Words

Selecting this option will cause the spell checker to ignore words beginning with a capital letter.

Ignore Words with Numbers

Selecting this option will cause the spell checker to ignore words containing numbers.

Ignore Words with Mixed Case

Selecting this option will cause the spell checker to ignore words containing letters of both upper and lower case.

Spell Checker Miscellaneous Options

Miscellaneous options for the spell checker are located under Advanced -> Configuration -> Spell Checker -> Miscellaneous.

The following options are available to you under this configuration item.

Spell As You Type

Selecting this will enable the Spell As You Type feature. More information on this feature is available in UltraEdit’s help files.

Display suggestions on right mouse click over misspelled word

Selecting this when Enable Spell Check as You Type is enabled will allow you to right-clickion a word shown as misspelled, and will result in a list of possible spelling options. If you prefer, the option Only if CTRL is pressed may be selected to restrict the display of these suggestions to the combination of pressing the CTRL key along with right clicking on a misspelled word. You may also specify a maximum number of suggestions to be displayed using the Display Suggestions (max) control. If this is set to “-1” then all available suggestions will be displayed.

Suggestion Mode

The suggestion mode may be set to “ultra”, “fast”, “normal”, or “bad-spellers”.

  • Ultra
    This method will use the fastest method available to come up with suggestions. This currently means that it will look for homonyms within one edit distance apart without doing any typo-analysis or using replacement tables. In this mode Aspell gets about 87% of the words from the small test kernel of misspelled words. (You can go to for more info on the test kernel as well as comparisons of this version of Aspell with previous versions and other spell checkers.)
  • Fast
    This method is like “ultra,” except that it performs typo-analysis and uses replacement tables. The typo-analysis brings words which are likely to be due to typos to the beginning of the list. This mode should get around the same number of words that the ultra method does.
  • Normal
    This method normally looks for homonyms within two edit distance apart and performs typo-analysis unless it is turned off. Is much slower than “fast” mode but it returns better suggestions. In this mode Aspell detects approximately 93% of the misspelled words.
  • Bad-Spellers
    This method also looks for homonyms within two edit distances apart but is tailored more for the bad speller, where as “fast” or “normal” are tailored more to strike a good balance between typos and true misspellings. This mode never performs typo-analysis and returns a huge number of words for the really bad spellers who can’t seem to get the spelling anything close to what it should be. If the misspelled word looks anything like the correct spelling it is bound to be found somewhere on the list of 100 or more suggestions. In this mode Aspell detects approximately 98% of misspelled words.


You may select the encoding to be used with the active dictionary from this dropdown.
