Research direction
The issue requests implementing Ctrl w in insert mode to delete the last word. Start by examining the current keybinding definitions in the repository, likely in files like 'src/keymap.js' or similar. Look at how other insert mode keybindings are handled, such as backspace. Consult CodeMirror's API for word based operations (e.g., 'deleteWordBackward'). Test the implementation to ensure it works without conflicts with the browser default (Ctrl w closes tab).
