On OS X you can use cmd+left/right to jump to the beginning/end of the line, or option+left/right to jump word by word. In just about every application.But not in the Terminal. Nor iTerm. You have to learn other, weird ways of jumping around... ctrl+a jumps you to the beginning of the line. ctrl+e is end of line. For jumping word-by-word it's ctrl+b or ctrl+f. The letters seem completely arbitrary.On Windows it's even worse  you can't even ctrl+c and ctrl+v. The official method for copying and pasting is insane.Why is this?NB. I'm not asking for help with configuring my terminal. I just want to understand why this situation exists.
Why don't terminals support standard keyboard shortcuts?
