Terminal shortcuts do not respond
Click the canvas or close the input panel to focus the intended area. Then try the same action using its button.
The terminal app may reserve Option, Command, or Shift+mouse combinations. Check its shortcut settings: the canvas can only act on events it receives. Plain drag selection, Hand, and the help panel provide alternatives.
In Warp, try Ctrl+Y to copy and Hand to pan. The terminal's own text selection is separate from a canvas range.
Agent cannot connect
Keep both the canvas page and Agent client open. Check connection status and permissions under Agent → Local MCP. After starting the server, wait for the connection before trying a read.
If a write times out, ask the Agent to read the canvas before retrying. Reconnecting does not mean the previous write failed to take effect.
A previous canvas is missing
Check whether you are using a different browser, profile, or website address. Terminal sessions are also separate from browser sessions. Return to the original environment and check its session list.
Do not clear site data to try to recover content. Reopen an exported file if available, and keep independent copies of important work.
Content is outside the view
Use the minimap or search to locate it. Panning does not delete text; avoid pasting duplicates while trying to find existing content.
A preview cannot be edited
The CLI's browser file preview is read-only. Use the terminal entry point to edit a native file, or import a copy into Web Canvas.
