Well, you could do: mapList reduce (_ ++ _) except for the special requirement for collision. Since you do have that special requirement, perhaps the best would be doing something like this (2.8): def combine(m1: Map, m2: Map): Map = { val k1 = Set(m1.keysIterator.toList: _*) val k2 = Set(m2.keysIterator.toList: _*) val intersection = k1 … Read more

If you find yourself using folds extensively, you could make some handy keybindings … Read more

You can close all folds with zM. If you have nested folds and you want to fold level by level, use zm. To open folds use zR (all) … Read more
There is a Fully Expand Tree Node action, which is bound to Numpad * key (*) by default. But if you use this key, it doesn’t expand the whole tree, rather it expands the first level and when you press it again it expands subsequent levels, and so on. But it can still do what … Read more
