[TenTec] Omni 7 hidden commands?

[denton sprague]

Hi all…
Was playing with my Omni 7 this am trying to find some kind of vfo lock…I keep  bumping the vfo knob and going off feq a bit….
Found out all I had to do was poke the blue ent  button and it apparently disengages the vfo knob…poking ent button again puts the feq display back to normal.
I don’t think this in the manual….
Anyone find any other little “easter eggs?"
