$CDPATH is a feature in many shells that allows configuring a list of paths to allow navigating to as if relative, regardless of their location. For example the environment variable CDPATH=/dev will allow you to navigate to /dev/vscode by running cd vscode, regardless of whether the shell is currently in /dev/ or not.

VS Code now supports this in its suggest widget. Set "terminal.integrated.suggest.enabled": true and a CDPATH environment variable to test this feature.

Test the following:

• ctrl+space can force the suggest widget to appear
• Note that you can export CDPATH=... and expect it to work provided environment reporting is working (terminal.integrated.shellIntegration.environmentReporting), this should be enabled by default in Insiders. If not, you would need to restart VS Code to source a new shell environment.
• It should work in any shell because of the default "terminal.integrated.suggest.cdPath": "absolute", even shells that don't support CDPATH
• CDPATH uses a ; path separator on Windows and a : path separator on non-Windows.
• Test each value of terminal.integrated.suggest.cdPath
• The completions should typically show up at the bottom of the completions list unless the input is a close match
