<p>In CFEclipse, I do a lot of double-clicking to select text. The standard behavior is to select all text within the nearest <em>word boundaries</em>. This is problematic when editing code where the original editor didn't use camel-case; for example, they wrote "myObject" as "my_object".</p>

<p>Is there a way to change the double-click selection behavior to include '_' as a valid <em>word</em> character?</p>

On eclipse 3.4.1 Ganymede, it seems to select the nearest boundaries
including
the '_' (at least in the java file I am using)
What eclipse version are you using ?
