Visual studio on Raspberry pi not working properly (TAb, CTRL+M, DEL, backspace not working)

Question

I'm using a raspbian Linux on a raspberry pi 4 2GB Ram through a VNC link to code C++ directly on it and control the GPIO pins.

I was coding with Geany until now which was working very fine, but it isn't really "evolved", therefore I wanted to switch to the Visual Studio Code

• When I tried to "TAB" a line to indent it, it did not work.
• Apparently, the solution is to press CTRL+M for switching the "Tab key moves focus"... Which did not work.
• I passed through the console to find the CTRL+M command and when activating it this way, nothing changes.
• I went to the "shortcut definition" and when I press "CTRL+M" it is detected as "CTRL+SHIFT"
• In the same idea, I tried to indent with CTRL+[ with no effect.
• Also, backspace and DEL are not working... DEL opens the "rename" function menu

Of course, all these were working with Geany.

VS Code seems to be a very nice upgrade compared to the Geany, but I'd like it to work properly with it.

Can anybody help?

Thanks in advance
