Show Phrases

Aurora Prediction has the unique ability to learn the phrases that you use to greatly speed up input and reduce the need for preprogrammed macros. So if you type "Fred Jones" several times, eventually it will learn to offer you "Fred Jones" as a single choice in the word prediction window. If you do not wish to have multiple word phrases offered in the prediction window, uncheck this option. Changing this option does not take effect until the next time you open a dictionary

Show Adult Words

Check this checkbox if you wish to have words that are marked as "adult" content presented in the Prediction window and the Dictionary Editor. Please see Adult Content for more information before checking this checkbox.

Show Phonetically Similar Words

Prediction has the ability to offer you words that sound like a word you are spelling if the word you are spelling is not in the dictionary. Typically this helps if you are spelling a word incorrectly. If the Use Color to Indicate Word Type checkbox is checked on the Window tab, these words will be drawn in the Prediction window in blue. Uncheck this if you do not wish to be offered similar sounding words in the prediction window. Changing this option does not take effect until the next time you open a dictionary.

Tip: Aurora Prediction will be much faster when typing if this option is turned off. A larger Dictionary Cache setting can mitigate this slowdown.

Don't Show Grammatically Incorrect Words

Prediction has the ability to apply grammatical rules to reduce the number of inappropriate words it offers in the prediction window. Uncheck this if you do not wish to have grammar rules applied to the prediction window. Changing this option does not take effect until the next time you open a dictionary.

Tip: In languages as complicated as English, it is very difficult to cover all cases with a finite set of grammatical rules. Aurora Prediction's prediction and guessing algorithms are very effective at presenting the correct words, you will generally receive best results if this feature is turned off.

Activate Prediction Automatically

If this checkbox is checked, Aurora Prediction will ask you if you wish to have Aurora Prediction help you with your typing in a new application when you type a word followed by a space in that application.


If you answer Yes, Prediction will start helping in that application. If you answer No, Prediction will not help in that window unless you use the manual Activate Window feature.

Do Automatic Spacing After Punctuation

Aurora Prediction automatically adds spaces after punctuation characters like .,?! Uncheck this checkbox to turn off the automatic spacing for punctuation.

Dictionary Cache

In general, the cache size of a dictionary should be about 25% of its uncompressed size. So if you have a 2 megabyte compressed dictionary on disk (the standard dictionaries shipped with Aurora are not compressed,) you should use 1024K(1M) of cache (2 megabyte dictionary file, double the size because it is compressed, and divide by 4). For a 2 megabyte uncompressed dictionary, you should select at least a 512K cache. If you have lots of RAM, you can only get better performance by choosing a larger cache. For an 8M RAM system, a minimum 1024K cache is recommended. For a 16M RAM system we recommend a 2048K cache. For a 32M system, you can go as high as an 8192K cache. Note that if you use a very large cache, you may not have enough memory left for Windows and your applications and you will see the system slow to swap the applications to and from disk. We recommend you play with this setting until you find the best balance of performance between Aurora Prediction and Windows and its applications. You may also want to see Optimizing the Dictionary for more information.

You can find out how your cache is performing in Dictionary Info from the Dictionary Editor.

Tip: You are not penalized if you choose a cache larger than the dictionary you are using needs. In that case Prediction will cache the entire dictionary and the balance of the cache will remain free for use by other applications.

Cache Entire Dictionary

If you are using a small dictionary, or have lots of RAM, check this option to get maximum performance from a dictionary. With this option checked, the entire dictionary will be loaded at startup. Note that this option may significantly increase the time needed to open a dictionary and if you do not have enough memory, it can make Windows and your other applications very slow.
