Apologies if I'm being stupid, but since a recent auto-update, the behaviour of holding option and ctrl with the cursor keys has altered; I think this is related to an item I noticed in a changelog.

That would probably be:

[CHANGED] The sub_word movement functions now also do CamelCase in addition to underscore_words. The default key bindings for these functions (move, select, and delete) have been changed to only use control as modifier (previously control + option was required) -- ticket 11746E04.

As it stands, Textmate is now using ctrl-left and ctrl-right for per-word selection, as opposed to option-left/option-right (unlike every other OSX app I have).

It does word movement on option, like any other OS X app, and it does sub-word on control, like Xcode, BBEdit, and Code Warrior (I think).

Similarly, double-clicking is now selecting a sentence, not a word. This is more than a mite annoying for most work I do, with both text and code.

This is not default -- did you alter word characters in preferences? It should just be an underscore. Maybe you added a space.

Is the behaviour I describe the default now, or has something odd happened on my install? If the former, how do I change it... and if the latter, how do I revert it?

I would suggest not reverting the sub word, it takes a week or two to relearn to use command for begin/end line stuff, but when you have learned it, you have 3 navigation tools instead of just two.

But for reverting it, the simplest is probably for you to just record a macro and save om ctrl left/right. See Key Bindings in the manual for other solutions.
