How to get "parameter hints" functionality

[md27182]

When I start typing a function and hit Ctrl + Shift + Space I don't get parameter hints as expected. Anyone know why this is?

Some logs might reveal why it's not working, especially the browser console logs: https://github.com/cdr/code-server/blob/main/docs/FAQ.md#how-do-i-debug-issues-with-code-server

Actually nevermind, I tested this in a Python and Typescript file and nothing happens. Nothing helpful in the logs either.

Ah nevermind, I got parameter hints and suggestions mixed up. Both are working for me on 3.9.1! Definitely post the logs when you get a chance.

Okay, I started a new code-server session (using the --link command) and opened the link in chrome on my local machine (running ChromeOS). Then I started typing a function that I had defined in my python file and hit Ctrl + Shift + Space, hoping to get parameter suggestions but nothing came up. I'm also on code-server 3.9.1.

Posting the console output below. Let me know if you need more info!

Bummer, nothing looks out of place there to me. Do you get the same issue in non-Python files?

I wonder if ChromeOS doesn't allow overriding these keys. It might be worth trying to rebind editor.action.triggerParameterHints to some other key sequence.
