* Blocks
The editor is separated into multiple /BLOCKS/. These blocks can be used to perform separate, related calculations. Each block can have a single output, which is the returned value from the block.

All blocks share the same global scope, meaning variables, functions, etc defined in a block are available to subsequent blocks.

* Modal editing

Abacus's editor is a modal editor that tries to follow VIM keybinds. The editor has two functional modes:

** Normal mode
In normal mode the cursor is a block and functional keybinds can be used for movement.
