The case change commands described here work on text in the current buffer. See Character Case, for case conversion commands that work on strings and characters. See Case Tables, for how to customize which characters are upper or lower case and how to convert them.
This function capitalizes all words in the region defined by
start and end. To capitalize means to convert each word’s
first character to upper case and convert the rest of each word to lower
case. The function returns nil
.
If one end of the region is in the middle of a word, the part of the word within the region is treated as an entire word.
When capitalize-region
is called interactively, start and
end are point and the mark, with the smallest first.
---------- Buffer: foo ---------- This is the contents of the 5th foo. ---------- Buffer: foo ----------
(capitalize-region 1 44) ⇒ nil ---------- Buffer: foo ---------- This Is The Contents Of The 5th Foo. ---------- Buffer: foo ----------
This function converts all of the letters in the region defined by
start and end to lower case. The function returns
nil
.
When downcase-region
is called interactively, start and
end are point and the mark, with the smallest first.
This function converts all of the letters in the region defined by
start and end to upper case. The function returns
nil
.
When upcase-region
is called interactively, start and
end are point and the mark, with the smallest first.
This function capitalizes count words after point, moving point
over as it does. To capitalize means to convert each word’s first
character to upper case and convert the rest of each word to lower case.
If count is negative, the function capitalizes the
-count previous words but does not move point. The value
is nil
.
If point is in the middle of a word, the part of the word before point is ignored when moving forward. The rest is treated as an entire word.
When capitalize-word
is called interactively, count is
set to the numeric prefix argument.
This function converts the count words after point to all lower
case, moving point over as it does. If count is negative, it
converts the -count previous words but does not move point.
The value is nil
.
When downcase-word
is called interactively, count is set
to the numeric prefix argument.
This function converts the count words after point to all upper
case, moving point over as it does. If count is negative, it
converts the -count previous words but does not move point.
The value is nil
