GitLens Remote Provider Settings for AWS CodeCommit

 If you wish to enable the shortcuts in GitLens to open remotes, as shown in the following screen shots, here is how I did it.

Screenshots of the shortcuts:

 

1. CTRL+SHIFT+P to open command palette.

2. Type Preferences: Open Settings (Json). Click on it to open the user settings file.

3. Add the following code, fixing the region values (As a Gist: gitlens.remotes.aws.md (github.com))

"gitlens.remotes": [{
        "regex": "https:\\/\\/(git-codecommit\\.us-west-2\\.amazonaws\\.com)\\/v1/repos\\/(.+)",
        "type": "Custom",
        "name": "AWS Code Commit",
        "protocol": "https",
        "urls": {
            "repository": "https://us-west-2.console.aws.amazon.com/codesuite/codecommit/repositories/${repo}/browse?region=us-west-2",
            "branches": "https://us-west-2.console.aws.amazon.com/codesuite/codecommit/repositories/${repo}/branches?region=us-west-2",
            "branch": "https://us-west-2.console.aws.amazon.com/codesuite/codecommit/repositories/${repo}/browse/refs/heads/${branch}?region=us-west-2", //
            "commit": "https://us-west-2.console.aws.amazon.com/codesuite/codecommit/repositories/${repo}/commit/${id}?region=us-west-2",
            "file": "https://us-west-2.console.aws.amazon.com/codesuite/codecommit/repositories/${repo}/browse/refs/heads/${branch}/--/${file}?region=us-west-2&lines=${line}",
            "fileInBranch": "https://us-west-2.console.aws.amazon.com/codesuite/codecommit/repositories/${repo}/browse/refs/heads/${branch}/--/${file}?region=us-west-2&lines=${line}",
            "fileInCommit": "https://us-west-2.console.aws.amazon.com/codesuite/codecommit/repositories/${repo}/browse/${id}/--/${file}?region=us-west-2&lines=${line}",
            "fileLine": "{line}",
            "fileRange": "${start}-${end}"
            }
        }]
