The behavior of double-click and option-arrow have recently changed for me (only in TextMate), and I'm finding the new behavior really annoying. For example, if I have the following Python code:

def my_function(parameter_name, defaults=None): #This is a test + another test ...

...then, 1) if I double-click on the "my" part of the function name, it select the string "def my"; 2) if I double-click on the word "test", it selects "This is a test ". Previously, #1 would have selected either "my" or "my_function" (I forget which) and, #2 would have selected only the word "test".

The option-left-arrow and option-right_arrow keys use similar "word" breaks when moving the cursor: if the cursor is in the word "test", for instance, option-left-arrow moves it to the beginning of the word "This".

It's not just a Python change, either. If I have the following text:

ALTER TABLE `my_table_name` MODIFY COLUMN `column_name` FLOAT NOT NULL;

...then double-clicking on the word "MODIFY" selects " MODIFY COLUMN ", for instance.

What might have changed to cause this annoying behavior, and how do I fix it?

I'd appreciate any suggestions,

Mike
