Viewing tabs in an editor in fedora 10

[Mark Ryden <markryde gmail com>]

Hello,
  I am looking for viewing tabs in an editor in fedora 10.
I know that this can be done with vim and vi (with :set list). (If I
remember correctly, also
with emacs).

However, I tried to achieve this task with other editors (like
jedit/gedit/kate) and
could not.
Any ideas if it is possible with other editors than vi/vim/emacs ?

Rgs,
Mark
