What do the basic checks do?
Chapter/verse numbers checks for missing and duplicated chapter and verse numbers.
Markers checks for invalid markers in the project.
Characters checks for characters marked as invalid or unknown in the character inventory. It is best to start with the characters inventory if you have not approved any characters in your language.
Punctuation checks for missing punctuation at the ends of paragraphs, also checks for any invalid punctuation or sequences of punctuation as defined in the punctuation inventory.
References checks \xt and \r and other markers that have a Scripture reference, that the reference matches the Scripture reference settings for the project.
Quoted text checks that text quoted in a footnote or cross reference matches what is in the text.
Capitalization checks for lower case letters after punctuation and markers that require upper case letters. You define which punctuation and which markers in your project do not require capitalization following in Markers followed by a lower case letter and Punctuation followed by a lower case letter in the Checking menu.
Repeated words looks for words repeated without intervening punctuation in the text. You can define valid sequences of words that repeat in Repeated words from the Checking menu.
Unmatched pairs of punctuation checks for pairs like open and close parentheses, open and closing square brackets and reports where an opening mark is missing the closing or a closing mark missing the opening mark. Does not check quotation marks, that is done by the quotation check.
Quotation checks that opening and close quotes and quotes within quotes match the rules defined in the Quotation Rules section of the Checking menu.
Numbers checks that numbers in the text match the Number setting rules in the Checking menu.
