Are there bookmarks in Visual Studio Code?

You need to do this via an extension as of the version 1.8.1.

1. Go to View → Extensions. This will open Extensions Panel.

2. Type bookmark to list all related extensions.

3. Install

I personally like "Numbered Bookmarks" - it is pretty simple and powerful.

Go to the line you need to create a bookmark.

Click Ctrl + Shift + [some number]

Ex: Ctrl + Shift + 2

Now you can jump to this line from anywhere by pressing Ctrl + number

Ex: Ctrl + 2

Yes, via extensions. Try Bookmarks extension on marketplace.visualstudio.com

Hit Ctrl+Shift+P and type the install extensions and press enter, then type Bookmark and press enter.

Next you may wish to customize what keys are used to make a bookmark and move to it. For that see this question.
