Your code would call the two item() methods several times, it's wastefull both at run time and when you typed it.

SWITCH: for ($Request->item("View")->item()) {
  if ($_ eq 'HowTo') { $str .= mHowTo(); last SWITCH;
  if ($_ eq 'Tutorials') { $str .= mTutorials(); last SWITCH;
  ...
}

It might be even better to use a hash like this:

my %actions = (
  HowTo => \&mHowTo,
  Tutorials => \&mTutorials,
  ...
);
...
sub tSupport {
  my $view = $Request->item("View")->item();
  
  return exists($actions{$view}) ? $actions{$view}->() : mSearch();
}
