iPadOS: Ctrl + C in terminal doesn’t kill running process

[jsjoeio]

Description

Hitting ctrl + c with the terminal focused and a process running (i.e. yarn start in a React app) does not kill the process.

If someone is able to provide a good starting point, I would be willing to take a stab at this.

• VSCode Version: 1.53.0-insider
• OS Version: iPadOS 14.1 (18A8395)
• Commit: 01089c0
• Date: 2021-01-07T05:25:51.740Z (16 hrs ago)

Steps to Reproduce:

1. On iPad, open Codespaces environment in Chrome
2. Open integrated Terminal
3. Start application (i.e. like a create-react-app - yarn start)
4. Focus terminal and hit ctrl + c

Expected

Process (yarn start) should stop running

Actual

Terminal receives new line

Does this issue occur when all extensions are disabled?: Yes

Perhaps that is not the right sigint.

One other piece of insight: this may not be limited to VSCode. @cdr has a product which includes a terminal in the browser. I’m able to reproduce the same issue (see line breaks at the bottom).

As a temporary workaround, it works if you manually define the shortcut like so:

1. Open Command Palette
2. Look for "Preferences: Open Keyboard Shortcuts (JSON)"
3. Add this:

{
    "key": "ctrl+c",
    "command": "workbench.action.terminal.sendSequence",
    "args": {
      "text": "\u0003"
    },
    "when": "terminalFocus"
}

I found the root reason was iPad Safari report keyCode of ctrl-c as 13, which is not correct, reference from MDN, keyCode is a deprecated property;

The key and code property is right, so I suggest just use key property, not keyCode, on the whole html page not just terminal.

@meganrogge I'm still seeing this in codespace, am I testing the right environment?

as another workaround, use ctrl+\ shortcut instead of ctrl+c, it will interrupt the process as well
