SUPPORTRV has an un-documented supplementary "stereo hotkeys" mode in which an additional set of stero-related hotkeys are active. You enter or leave the mode with Alt-s (Option-s on Mac). While the mode is active, these additional hotkeys are available:
a Anaglyph Mode
d Checked Mode
k Scanline Mode
s Side-by-Side Mode
p Side-by-Side Stereo Mode
m Mirrored Side-by-Side Stereo Mode
x Stereo Mode Off (DEPRECATED -- use alt-s (or option-s on the mac))
h Hardware Stereo Mode
, Left Eye Only Stereo Mode
. Right Eye Only Stereo Mode
< Left Eye Only Stereo Mode
> Right Eye Only Stereo Mode
S Swap Eyes
o Edit Global Relative Stereo Offset
As of RV 3.10.2, we've added these hotkeys to the list above:
z Horizontal Squeezed Stereo Mode
v Vertical Squeezed Stereo Mode
r Edit Global Right-Eye Stereo Offset
As of RV 3.12.11, we added a hotkey to turn stereo off, especially useful in Presentation Mode:
f Turn OFF Stereo Display Mode (in Controller Window)
As of RV 3.12.15, we changed the hotkey to turn stereo off, since "f" conflicts with frame. We also added "/" to reset stereo offsets:
O Turn OFF Stereo Display Mode (in Controller Window)
/ Reset Stereo Offsets
As of RV 3.12.19, we added a couple hotkeys to control the per-clip (per-source) stereo offset:
c Edit Source/Clip Stereo Offset
R Edit Source/Clip Right-Eye-Only Stereo Offset
