[TxMt] How to highlight all instances of a variable in TextMate?

[Markus Banfi]

If you place the cursor on a variable in NetBeans (at least in Ruby
code) it highlights all instances of that variable. This is a feature
I like very much.

Does TextMate or some bundle have a similar feature?


I have also asked this question on StackOverflow. If anyone wants to
get some points there:
