You're right to assume that they probably have their own set of preferred tools and techniques for navigating source code. When I need to pair up or collaborate with my team, I've had good success with VS Code's
$1 extension. Similar to Google Docs, each participant can join a Live Share session from their own workstations. When I join the session, I'm able to use my accessibility tools and shortcuts the way I want without impacting others, or having to install specialty software on their workstations.
It's important to note that Live Share uses some cloud services to function, so be wary of your organization's security policies.
