I'm new here. This is my first post. It's a question
Welcome to the list :)
Could someone please suggest why whenever I press the tab key
to indent, the whitespace is coloured red? How can I get rid
of this?
There are a couple possibilities:
1) you're editing a file whose syntax-highlighting definition
prescribes highlighting whitespace
2) you've got search-highlighting triggered (usually by (a)
having it enabled and (b) searching for a tab)
3) you've got a syntax-match specified.
To solve #2, you can
1) search for something different
2) temporarily disable search highlightin (":noh")
3) turn it off all-together (":set nohls")
To solve #3, you can
:match none
Solving #1 is a little trickier, as it depends on what your
current syntax/file-type is:
:set ft?
By knowing the filetype, one can track down how the mapping to a
color is getting created, and how to override that color.
If #2 and #3 don't solve the problem, the ":set ft?" results will
help track down what's going on.
