AWS CodeWhisperer and GitHub Copilot don't get along in VSCode. Rejecting code suggestions sometimes triggers the pop-up (repeatedly) "command aws.codeWhisperer.rejectCodeSuggestion not found." This is especially annoying when using Vim since it breaks the Escape key which is interpreted by VSCode as rejecting code suggestions. Go to Command Palette (Command+Shift+P) Search for: Open Keyboard Shortcuts (JSON) Add: { "key": "escape", "command": "-aws.codeWhisperer.rejectCodeSuggestion", "when": "aws.codewhisperer.connected && inlineSuggestionVisible && !editorReadonly || isCloud9 && suggestWidgetVisible && !editorReadonly" } Restart VS code
