iTerm --> solved
What is "iTerm"?
I bought a Mac in Switzerland, and the keyboard shortcuts to get {, }, #, /, \, etc. needed for scripting was so completely rubbish so I had to buy an English keyboard, where all those characters have their own keys, and at most, Shift is the only other key you need!
Otherwise it's like playing twister with your fingers.
The moral: Apple are useless at designing keyboards! Real ones and virtual ones.
