I just learned through a webinar yesterday on shortcut keys for toggling the Reverse-Interlinear on and off.
Mac: cmd-i : to toggle the inline reverse-interlinear; shift-cmd-r: to toggle the bottom reverse-interlinear
PC: ctrl-i: to toggle the inline reverse-interlinear; shift-ctrl-r: t toggle the bottom reverse-interlinear.
This helped some of my frustration with the new toolbar.
I've tried this on my MAC, it works, I have not tested on my PC yet.
Hope this helps others.
