Secret features in single track mode (T)

[bjorgan]

We have some secret, undocumented features which would be nice to make more intuitive from the user interface by displaying hints.

List of implemented features (scrutinized from the code in SingleTrack()):

• Key left/key right or +/- key switches the tracked satellite
• Space switches between the transponders
• Key down (or <)/key up (or >) shifts the uplink and downlink frequencies by 1 kHz steps between defined start and end frequencies
• ,/. does the same as above, but in 100 Hz steps
• d/D and u/U turns on/off downlink/uplink updates to rigctld (f turns on both)
• F/f forces a read of the downlink and uplink frequencies from rigctl (overwrites corresponding variables)
• f turns on downlink and uplink updates to rigctld
• m/M turns on/off automatic frequency reading from rigctl. Frequencies are read from rigctld, inversely rectified against doppler shift and set to canonical downlink and uplink frequencies. Similar to F above, but does this continuously.
• x reverses VFO of downlink/uplink
• Q/q/ESC escapes single track mode

Other views are either intuitive or do not have secret keys.
