Keyboard Shortcuts

The simulator is fully keyboard-navigable. All shortcuts work globally — you do not need to focus a specific panel first.

Open the shortcuts dialog at any time with Ctrl+/ or by clicking the keyboard icon (⌨) in the header.

Panels

Shortcut	Action
`Ctrl` + `	Toggle Log Panel open / closed
`Ctrl` + `1`	Toggle Config Panel open / closed

Charger

Shortcut	Action
`Alt` + `C`	New charger — adds a new tab with default settings
`Ctrl` + `Enter`	Connect / Disconnect the active charger

Ctrl+N and Ctrl+Shift+N are reserved by Chromium-based browsers (new window / incognito) and cannot be overridden by web applications. Alt+C is used instead as it is not intercepted at the browser level.

Logs

Shortcut	Action
`Ctrl` + `S`	Export logs as JSON — downloads `ocpp_logs_<timestamp>.json`
`Ctrl` + `Shift` + `S`	Export logs as CSV — downloads `ocpp_logs_<timestamp>.csv`

The CSV export includes the following columns:

Column	Description
`timestamp`	ISO 8601 timestamp of the log entry
`direction`	`Tx`, `Rx`, `Error`, or `System`
`action`	OCPP action name (e.g. `BootNotification`)
`raw_message`	The raw OCPP-J frame as a JSON string
`payload`	The parsed payload object serialized to JSON

All fields are properly quoted to handle commas and newlines inside JSON payloads.

Shortcuts Dialog

Shortcut	Action
`Ctrl` + `/`	Open / close the shortcuts dialog
`Esc`	Close the dialog

Browser Compatibility

Some shortcuts may be intercepted by the browser or OS before reaching the simulator. The table below shows tested behaviour in common browsers on Windows:

Shortcut	Chrome	Brave	Firefox	Edge
`Ctrl+``	✅	✅	✅	✅
`Ctrl+1`	✅	✅	✅	✅
`Alt+C`	✅	✅	✅	✅
`Ctrl+Enter`	✅	✅	✅	✅
`Ctrl+S`	✅	✅	✅	✅
`Ctrl+Shift+S`	✅	✅	✅	✅
`Ctrl+/`	✅	✅	✅	✅

Ctrl+S in browsers normally triggers the browser's Save Page dialog. The simulator calls event.preventDefault() synchronously before any async work, which successfully suppresses this in all major browsers.
