Toggles the system metrics panel — a draggable floating overlay that shows real-time connection health. Tap the key to show or hide it. The system meter is included by default in both the desktop and mobile layouts.
Metrics
The panel displays four metrics, each shown over three time windows (1 minute, 5 minutes, 10 minutes):
RTT (Round-Trip Time)
Network latency between client and server, in milliseconds.
FPS (Frames Per Second)
The current target refresh rate for terminal screen updates, automatically adapted based on RTT.
Data In
Total raw bytes received from the server (terminal output, state updates) summed over each time window.
Data Out
Total raw bytes sent to the server (keyboard input, resize events) summed over each time window.
All four metrics are explained in detail on the Adaptive Protocol page.
