Zoom in/out/fit key combos like PS/LR/FRV/browsers/other image editors

PS, LR, browsers, and may other image editors use the following key combos
[ctl][+] = zoom in
[ctl] = zoom out
[ctl][0] = fit to screen

Could we either have the same - or have a way in settings (or in an ini/XML file) to make them work this way? I’m switching between FastRawViewer, PL and PS - and only PL works differently. As I remember, even the NIK plugins zoom with these key combinations…

For DxO it’s mouse roulette.
Why does Adobe not the same useful interface?
