fix(keyboard): parse keyboard input without nesting

[ph-fritsche]

What:

Simplify the parsing and iterating through key defs.

Why:

Previous implementation nested calls. This could lead to RangeError: Maximum call stack size exceeded.

How:

Parse first and then iterate through parsed defs like the pointer implementation already does.
