This is working perfectly in CS6 and WAS working in CC as well.... until today....
The double-click function was broken in CC2014. You must have just upgraded?
You'll have to use scripting to get a true 1:1.
In Applescript it's:
tell application "Adobe InDesign CS6"
set x to main monitor ppi of general preferences
set zoom percentage of active window to (72 / x) * 100
end tell
And in Javascript this should work:
var x = app.generalPreferences.mainMonitorPpi
app.activeWindow.zoomPercentage= (72 / x) * 100
You can assign key commands to scripts.
