Cycles VS Code global proxy settings: each entry in vsxdt.proxyList, then no proxy, then system proxy, then repeats—useful for rotating HTTP(S) proxies without opening Settings.
Open Settings → vsxdt → Proxy List, click Add Item: Item = proxy address, Value = hex color (e.g. #4caf50). Or run DevTools: Manage Proxy List.
Run DevTools: Cycle Proxy from the Command Palette, or press Alt+Shift+P if not bound elsewhere.
A permanent status-bar ring (SwitchyOmega-style) shows the active mode:
Colored ring — that proxy is in use (http.proxy set; color from the entry or a default)
Gray ring — no proxy (http.proxySupport off)
Black ring — system proxy (empty http.proxy, http.proxySupport override); included in the cycle only when Include system proxy is enabled
If vsxdt.proxyList is empty, the cycle command offers to open the manager. Click the status-bar item to cycle.
