Hello,
renaming in 3dsmax is tedious, it should be possible as in most other softwares:
They have a convention, that renaming is done by a fast double-click (including Maya, Aftereffects, Substance...)
Of course the selection of subobjects is currently also done in 3dsMax by fast double-clicking, but it could be then a combination of Shift+fast double click or something else.
Currently, it's even not possible to assign a hotkey to rename an object, but this is such a basic frequent task and the current slowly double-click is much too time-consuming when trying to work fast.
To assign for anything such a slowly double-click makes to me no sense at all.
In general, it would be great to unify hotkeys as much as possible, especially if want to attract people from Maya or other softwares 😉
