I downloaded the file and copied it to the C:\Users\a.vscode\extensions folder. I can see that the plugin is installed on the VSCode extension page.
When I press F1, VSCODE prompts:command'extension.multiCommand.execute' not found
The path to my keybindings.json is C/users/a/AppData/Roaming/VSCode/user/keybindings.json
The path to my settings.json is:
C/users/a/AppData/Roaming/VSCode/user/setting.json
Look for the answer.
I would love to be able to use this extension
