Sorting

The sort-buffer command lets you sort the lines of the current buffer. The command asks for the name of a buffer in which to place the sorted output. The sort-region command sorts the part of the current buffer between point and mark, in place. The commands reverse-sort-buffer and reverse-sort-region operate like the above commands, but reverse the sorting order.

By default, all the sorting commands sort the lines by considering all the characters in the line. If you prefix a numeric argument of n to any of these commands, they will compare lines starting at column n.

When comparing lines of text during sorting, Epsilon normally folds lower case letters to upper case before comparison, if the case-fold variable has a nonzero value. If the case-fold variable has a value of 0, Epsilon compares characters as-is. However, setting the buffer-specific sort-case-fold variable to 0 or 1 overrides the case-fold variable, for sorting purposes. By default, sort-case-fold has a value of 2, which means to defer to case-fold.

Standard bindings:

			sort-buffer
			sort-region
			reverse-sort-buffer
			reverse-sort-region
