Keyboard shortcuts & the terminal
Once you are connected, you can drive the whole radio from the keyboard, and watch what the app is doing in a built-in terminal. Both are handy for power users and for troubleshooting.
Keyboard shortcuts
The arrow keys tune and change volume; Enter is the encoder click; and letter keys cover band, mode, step, bandwidth, AGC, backlight, calibration, sleep, logging and screenshots. Press the help button (or ?) to see the full key map at any time. Shortcuts are ignored while you are typing in a field, so they will not fire when you are entering a frequency.
The terminal
The collapsible terminal logs what the app does: tuning steps, uploads, screenshots, errors, newest at the bottom, with auto-scroll. You can clear it or export it to a text file. When something is not behaving, the terminal usually shows why.
