Bug 66501 [typing] In smart mode: Delete Next/Previous Word delete selection
200406092000 In the java editor, Delete Next Word (Ctrl+Delete) and Delete Previous Word (Ctrl+Backspace) behave unexpected. They should always just delete the selection iff it is not zero-length. That's the behavior we're used to with unmodified Delete and Backspace, and it's also what the Text Editor already does. void foo() { System.out.println(123); } Set cursor to before "out.", then press 2x Ctrl+Shift+Right to select "out." with the caret after the selection. Expected: Ctrl+Delete deletes selection. Was: Ctrl+Delete then deletes "println", leaving the selection alone. Similar problems with Ctrl+Backspace and when caret is at the start of the selection.
