Answer 3

The Visual Studio extension Productivity Power Tools 2015 from Microsoft has a feature called Quick Launch Tasks that adds new commands to the Quick Launch menu. One of them is CollapseRegions and it does exactly that.

The opposite command is ExpandRegions and it expands all regions for quick browsing of the entire file. These commands can be used pretty quickly by pressing the CtrlQ hotkey and typing Coll resp. Exp, then pressing Enter (supposed you don't have other commands with the same prefix).

Answer 4

Looks like the closest thing is Ctrl+M, Ctrl+S

Which will collapse the current region you are in, while Ctrl+M, Ctrl+E will expand the current region you are in.
