I think I'll hold off making change to 'translatestrings' until Adobe fixes. Who knows, the may also change the 'lock zoom' conflict at same time....at least I hope they would.
Actual, I did create the translatestrings file as suggested. All secondary controls now work///zoom in/out and zoom 100%.
What is missing is "Toogle" This is VERY important. On primart display, right clicking on screen or pressing 'Z' will toogle between last two screen sizes, for example FIT and 100%. On secondary display, you get the same action by right clicking on screen, but I cannot find any keyboard shortcut.
It's an issue on Mac too. I'm finding (using Mac keyboard with numeric keypad built-in) the behavior is different depending on where you hit the key(s) - most don't work as expected.
I did an analysis testing Cmd-Shft-character (the view mentioned is the one in the Second Display pop-up):
Grid - none work
Loupe - Normal - works using top-line on keyboard, numpad gives (0)
Loupe - Live - works using top-line on keyboard, numpad gives (1)
Loupe - Locked - works using top-line on keyboard, numpad gives (0)
Compare - works using top-line on keyboard, numpad gives (1)
Survey - none work
Slideshow - none work using top-line on keyboard, numpad gives (2)
