VSCode extension API for keybindings

This link should show you how to do it. https://code.visualstudio.com/api/references/contribution-points#contributes.keybindings

Steps:

1. register a new command (in extenson.ts)

   let disposable = vscode.commands.registerCommand('extension.helloWorld', () => {
     console.log("command ran");
   });
   context.subscriptions.push(disposable);`
   

2. Then add it to the activation events (in package.json)

   "activationEvents": [
     "onCommand:extension.helloWorld",
     "onCommand:extension.newComment"
   ],
   

3. Then declare your new command (in package.json)

   "contributes": {
     "commands": [{
       "command": "extension.helloWorld",
       "title": "Hello World"
     }],
     "keybindings": [{
       "command": "extension.helloWorld",
       "key": "ctrl+k ctrl+k",
       "mac": "cmd+k cmd+k",
       "when": "editorTextFocus"
     }]
   },
   

Now whenever someone double presses k while holding cmd, the helloWorld command will run and "command ran" will be print to the console.

You can do that by contributing all of your keybindings and using a custom where clause. See https://code.visualstudio.com/api/references/when-clause-contexts#add-a-custom-when-clause-context
