Epsilon has several commands
that operate on words. A word usually consists of a sequence of
letters, numbers, and underscores. The Alt-F and Alt-B commands move
forward and backward by words, and the Alt-D and
Alt-<Backspace> commands kill forward and backward by words,
respectively. Like all killing commands, they save away what they
erase (see Killing Text for a discussion on the killing
commands). Epsilon's word commands work by moving in the appropriate
direction until they encounter a word edge.
The word commands use a regular expression to define the current
notion of a word. They use the buffer-specific variable
word-pattern. This allows different modes to have different
notions of what constitutes a word. Most built-in modes, however,
make word-pattern refer to the variable default-word,
which you can modify. See Regular Expressions for information on
regular expressions, and Variables for information on
setting this variable.
You can set the forward-word-to-start variable nonzero if you
want Epsilon to stop at the start of a word instead of at its end when
