This is an incredibly trivial bug report, but it does bug me, if only a teeny, teeny bit. This is on a Mac running Sublime Text 2 Version 2.0.1, Build 2217 on Mountain Lion.

Create a new document. Hit Save. A dialog appears with a text field for the desired file name.

The ^K keyboard shortcut does not delete to end-of-paragraph, as it does in any standard Cocoa text field. That’s all; that’s the bug.

I’m guessing this is because the app explicitly maps ^K to “Delete to End” in the Edit menu, instead of relying on the built-in Cocoa behavior.
