answer rolling for April 2021
to focus to your differents panel of VSCode you have to edit your "workbench" commands :
CTRL+K+CTRL+S otherwise Files> Preferences> Keyboard Shortcut
look for this command
workbench.action.terminal.focus
to focus to your code you have to set the following command
workbench.action.focusActiveEditorGroup
to focus into the file explorer of vscode you have to set the following command
workbench.files.focusFilesExplorer
and no more need to search to the mouse or to quit your keyboard for the touchpad
That's all folks ! Hope you will spend less energy on your touchpad ... !
