What is the keyboard shortcut for ⇒ in your Scala editor of choice?

Question

The Unicode operator \u21D2 "⇒" (sometimes writtten as =>) is a common lexical identifier prevalent in the Scala programming language used in functional combinators, function definitions, case-match statements, etc. I normally have to copy-and-paste this operator into my code from someplace else, but that can get really annoying.

Does anyone know of shortcuts to produce this symbol in your IDE of choice? I typically use programs like JetBrains IntelliJ, SublimeText, and VIM.

Answer 1

For emacs, there's (global-prettify-symbols-mode), which just displays ⇒ over =>. It still writes => to the file in the end.

Answer 2

In IntelliJ IDEA under

Preferences -> Editor -> CodeStyle -> Scala

In the Tab 'Other' are options to automatically insert several unicode characters.

Answer 3

In IntelliJ, I've created a live template of the form $PARAMS$ ⇒ $BODY$. This lets you easily insert the ⇒ character.
