'isk' contains a list of characters (or character-ranges) for those
characters that should be considered a "word". This comes into play
when using "\<", "\>", "\k" and "\K" in a regular expression; what
gets considered when you use "*" and "#" to search; what the "iw" and
"aw" text-objects select; what's considered a "w"ord motion; how
abbreviations are found; and plenty of other places.
For example, by default "-" isn't part of the 'isk' setting, but if
you wanted "vip" to highlight/select whole CSS selectors like
"background-color"
:set isk+=-
to add the dash. Now, if you do "viw" anywhere in the attribute,
it will highlight/select the entire "background-color" not just
"background" or "color".
It's a little tricky to add certain characters as they have special
meaning. The easiest way I've found is to make a range of length one
for "@":
:set isk+=@-@ " add an at-sign, good for email addresses
" and Python decorators
