When invoking PowerShell: ScriptAnalyzer Rules from the settings menu, it would be nice to be able to enable/disable each rule by arrowing up and down and hitting spacebar to change the status.

This is also something that VS Code controls as part of the showQuickPick API. They prioritize any keys other than Enter as input because typing allows you to filter the selections. You might be able to file an issue at their repo to ask about it but my assumption is that they'll want to keep it as-is.
