\~

  • In order to prevent some browser specific problems with whitespaces, it is advisable to use ~ (tilde) as the whitespace instead of the normal blank key (in places where whitespaces are mandatory, e.g. after commands).
  • Ex.: $$\frac~xy$ to produce \frac~xy$$
  • Ex.: $$\sqrt~n$ to produce \sqrt~n$$
