The Spell Checking tab is part of the Preferences window.
Choose the dictionaries you wish to include. It is recommended that you use UK or US spelling consistently, so only enable both sets if you have a valid reason.
This file stores all words you add to the spell checker.
To reset the user dictionary to the default, locate the file and delete it. RevMan will then automatically create a new file the next time you run the spell checker.
Set options for:
Text that should be ignored.
Whether doubled words and case should be taken into account.
Whether split word should be suggested. For example if "large scale" should be suggested for "largescale".
