When trying to, e.g., rename variables, the actions within the refactor context menu are disabled. Keybinds for these actions are also disabled. I tried this with PTVS 2.0 and 2.1 beta in Visual Studio 2013.
I do also have ReSharper installed, but I would hope that doesn't interfere with PTVS.
Anyone have a guess about what causes this?
ReSharper is to blame.
Disabling ReSharper via Tools > Options > ReSharper restores the ability to refactor Python code.
Edit: Another option is to go to ReSharper > Options > Keyboard & Menus
Untick Hide overridden Visual Studio menu items
This restores the built-in refactor menu and also allows using refactor keybinds.
