cmd+k cmd+k shortcut

[roblourens]

We recently added cmd+k cmd+k as a shortcut for "Toggle Fold" but some of us were thinking that it is not a good choice. It is easy to trigger on accident while trying to hit another chord, and it could be very confusing to someone if their code disappears and they don't know how to unfold it.

Also, this shortcut is already used in the keyboard shortcuts JSON editor to add a shortcut, and this now breaks that and triggers Fold instead.

I think we should leave cmd+k cmd+k unbound, also k isn't anywhere in "toggle fold" so it doesn't seem like an intuitive choice anyway.

Visual Studio uses Ctrl + M - Ctrl + M, and that's why I ended up with Ctrl + K Ctrl + K.
I'm fine to change it

I change it to Ctrl + M - Ctrl + L
