You can use control-w to close a vscode tab, just like chrome.
Also if you use the following custom keybindings you can go between tabs with control-1/2/3 like chrome:
{ "key": "ctrl+1", "command": "workbench.action.openEditorAtIndex1" }, { "key": "ctrl+2", "command": "workbench.action.openEditorAtIndex2" }, { "key": "ctrl+3", "command": "workbench.action.openEditorAtIndex3" }, { "key": "ctrl+4", "command": "workbench.action.openEditorAtIndex4" }, { "key": "ctrl+5", "command": "workbench.action.openEditorAtIndex5" }, { "key": "ctrl+6", "command": "workbench.action.openEditorAtIndex6" }, { "key": "ctrl+7", "command": "workbench.action.openEditorAtIndex7" }, { "key": "ctrl+8", "command": "workbench.action.openEditorAtIndex8" }, { "key": "ctrl+9", "command": "workbench.action.openEditorAtIndex9" },
