I don't find any shortcut to create a snapshot in Camera raw. Strange, as there are shortcuts for almost everything, including the most exotic operations. 3 clics are needed to create a snapshot : open snapshot panel, clic on icon below, clic to confirm name of snapshot...
It would also be nice to have the opportunity to ask in preferences "create a snapshot as I open an image". Or, why not a history of adjustements like in Lightroom ?
Totally agree. Presets too.
You still need to clock OK after typing in the snapshot name.
And Ctrl-Shift-P does Presets too.
