Insertions (abxcd v. abcd)
This rule looks for 1 extra letter which may be inserted, e.g. HOWWEVER
Swapped letters (abcd v. acbd)
This rule looks for letters which have got swapped, e.g. HOVEWER
1 letter difference (abcd v. abxd)
This rule looks for a 1 letter difference, e.g. HOWEXER
Anagrams too (abcd v. adbc)
This rule looks for the same letters in a different order, e.g. HWVROEE
end letters to ignore if at last letter:
This rule allows you to specify any letters to ignore if at the end of the word, e.g. if you specify "s", the possibility of a typo when comparing ELEPHANT and ELEPHANTS will not be reported.
minimum start-of-word match
This setting (default =1) allows you to assume that when looking for minimal pairs there is a part of each at the beginning which matches perfectly. For example, when considering ALEADY, the program probably doesn't need to look beyond words beginning with A for minimal pairs. If the setting is 1, it will not find BLEADY as a minimal pair. To check all words, take the setting down to 0. The program will be 26 times slower as a result!
minimum word length
This setting specifies the minimum word length for the program to consider the possibility there is a typo. The default is 5, which means 4-letter words will be simply ignored. This is to speed up processing, and because most typos probably occur in longer words.
all words starting with …
If you choose this option, the program will ignore the next setting (max. word frequency). Here you can type in a sequence such as F,G,H and if so, the program will take all words beginning F or G or H (whatever their frequency) and look for minimal pairs based on the rules and settings above.
max. word frequency
(ignored if "all words starting with" is checked) How frequent can a typo be? This will depend on how much text your word-list is based on. The default is 10, which means that any word which appears 11 times is assumed to be OK, not a typo.
