I’m using a Chromebook, and I cannot execute some shortcuts (even when redefining them), like the one for duplicating the current line. It appears (in the program chart) to be defined as Ctrl+Alt+Shift+, but… it doesn’t work for me. I tried redifining it in a simplier way, such as Ctrl+… with the same result: nothing happened.
Ctrl + Shift + P will bring up the command palette in VS Code. From there, you can scroll the list and manually select the command you are looking for.
