Examples:

# open port selection screen

stuart -b 9600 /dev/ttyUSB0

Key Bindings

Port Selection

Key	Action
`↑` / `↓` / `j` / `k`	Navigate
`Enter`	Open port
`s`	Settings
`r`	Refresh port list
`q`	Quit

Terminal - Control Mode

Enter control mode with Ctrl+Esc or Ctrl+Space.

[!NOTE] For Ctrl+Esc to work, your terminal emulator has to support the kitty keyboard protocol, which most modern emulators do. If not, only Ctrl+Space will work.

Key	Action
`a` / `i`	Enter insert mode
`↑` / `↓` / `j` / `k`	Scroll
`Esc`	Scroll to bottom
`f`	Flush screen
`c`	Copy scrollback to clipboard
`+` / `-`	Cycle baud rate
`s`	Settings
`Del`	Disconnect → port select
`q`	Quit

Terminal - Insert Mode

All keypresses are forwarded to the device. Press Ctrl+Esc to return to control mode.

Settings

Key	Action
`↑` / `↓`	Navigate
`←` / `→`	Cycle value
`Enter`	Edit baud rate (type custom value)
`Esc`	Close
