Have optional buttons which are usually capacitive touch which perform the functions:
  - toggle main display and wind speed history
  - toggle main display and barometer history.
  - both buttons:  configuration mode is entered/exited

In history mode, the other button toggles timescale

In configuration mode use first button to go to next item, second button to change setting.

It is possible to configure from a serial console without the buttons or screen.  For this use minicom, eg:
minicom -D /dev/ttyUSB0 -b 38400
and type "config" to enter configuration mode.
