How to select current word in Visual Studio Code (VS Code)?

Question

On Mac OS: Cmd+D
On Windows & Linux: Ctrl+D

Above solved the purpose for me.

But ⌘D is defined as "editor.action.addSelectionToNextFindMatch", so if you press it more than once, it will try to search and select same word in the file which then can be used to do "multi word editing".

You are looking for Shrink/Expand Selection.

Trigger it with Shift+ Alt+Left and Shift + Alt+Right

Update:

This is now called Smart select API. This feature uses semantic knowledge to intelligently expand selections for expressions, types, statements, classes, and imports.

If you want to ctrl+w to behave the same as in Idea just go keyboard settings

Search for Expand selection. Set new shortcut cmd+w or ctrl+w depending on your OS. Also re-bind other commands that use ctrl+w to use another shortcut that you want, for example cmd+f4

You can edit keybindings.json to avoid using UI.

It is Ctrl + D that works for me in latest Visual Studio Code on Windows.

Go to File -> Preferences -> Keyboard shortcuts, you will find this:
