Two different things!

Escaping the dollar means that variable interpolation won't happen and only literal '$zoek' can match.

quotemeta on the other hand escapes regex metas after inserting the content of $zoek

"zoek" is Dutch for "search" and is literal user input via Tk. But a $ in input is also a meta which needs to be quoted.

 
main::(-e:1):   0
  DB<1> $x='.'

  DB<2> p 'a' =~ /$x/
1
  DB<3> p 'a' =~ /\Q$x/

  DB<4> p '.' =~ /\Q$x/
1
  DB<5> p '.' =~ /$x/
1
  DB<6> p '.' =~ /\$x/

  DB<7> p '$x' =~ /\$x/
1
  DB<8>
