AI Suggested Code Completion
You can ask Wing Pro's AI integration to suggest code appropriate for your current insertion point in the editor at any time by pressing Ctrl-? or Ctrl-Tab. This enters AI suggestion mode and sends a request off to the AI provider.
The request to the AI provider may take quite a while to complete, depending on the complexity of the problem, but generally produces code that would take far longer to write manually. Wing shows the status of the request in the status area in the bottom left of its window.
Once a result is available, it is placed into the editor in provisional form and the editor enters into AI suggestion mode. If you don't like the suggestion, you can press Ctrl-? again (or Tab while still in AI suggestion mode) to request another suggestion. This can be done repeatedly, and you can traverse suggestions that you have requested with Shift-Tab to move backwards and Tab to move forwards. Then press Enter to accept the current suggestion or Esc (or Ctrl-G or Esc Esc in Emacs mode) to cancel and exit AI suggestion mode.
A single Undo will undo any changes inserted into the editor if you decide you did not want the suggestion after you have already accepted it.
Note that moving the caret in the editor while waiting for an AI suggestion will automatically cancel the pending request and exit AI suggestion mode.
Context
By default Wing sends only part or all of the current file with your AI suggestion request. If the code you
want the AI to write needs to know about other code in your project, you can ask Wing to include
that by setting up and selecting an AI context from the AI Suggestion Context item in the AI menu
or the AI Suggestion Context icon 
in the top right of the editor. See AI Request Context for details.
Quality of Results
The AI suggestion capability is useful primarily for filling in implementations where the amount of code expected is relatively small and the requirements for it are obvious from the surrounding existing code. When this is not the case, it is much better to use the AI Coder tool to describe exactly what you want in more detail.
Key Binding
If you prefer a different key binding for this feature, you can bind the command ai-suggest-next to any key sequence with the User Interface > Keyboard > Custom Key Bindings preference.
