On the Language tab in the dialog box of the ribbon command File | Options 
, you can make settings for Presentations' language tools:
Default language
Here, you can select the language to be used for spell check, hyphenation and the thesaurus. To do so, open the dropdown list and select the desired language from the available options.
Note: Please note that there are two entries in this list for German:
▪"German (Germany)" stands for the new spelling (according to the 1996 German spelling reform in its last revision in 2006).
▪"German (Germany, old)", on the other hand, stands for the old spelling.
The same applies to "German (Austria)" and "German (Switzerland)".
Spell check
Here, you can specify whether Presentations should automatically check the spelling of text. The following settings are available:
▪Check spelling as you type
| If you enable this option, the spelling of the entire document will be continuously checked in the background. Incorrectly spelled words are indicated with wavy red underlines and can be corrected at any time. For more information, see Checking the spelling as you type. |
| Note: If this option is disabled, you don't have to do without a spell check – you can always start it manually with the ribbon command Slide show | Spell check. For more information, see Manual spell check. |
▪Color
| Here, you can change the color of the red underlines used by the function "Check spelling as you type" to indicate misspelled words. |
▪Underline old German spellings in blue
| If this option is enabled, the function Check spelling as you type also underlines with a blue wavy line all words that correspond to the old German spelling but should be spelled differently according to the new spelling of the spelling reform of 1996. For more information, see also Conversion to the new German spelling. |
| Note: This option only works for text in the language "German (Germany)", "German (Austria)" or "German (Switzerland)". |
▪Ignore words that start with a number
| If you enable this option, the spell check ignores all words that start with a number (for example, "1980s"). |
▪Manage dictionaries
FreeOffice: SoftMaker FreeOffice does not have the premium SoftMaker dictionaries normally included in SoftMaker Office. Only Hunspell dictionaries can be used here.
| As an alternative to its own dictionaries, SoftMaker Office also supports the use of Hunspell dictionaries. They are available free of charge for installation. Most of them were created by private users or non-profit organizations. |
| The Manage dictionaries button allows you to install dictionaries and also specify which of these dictionaries should be used for a language. For more information, see Installing dictionaries. |
