<blockquote>
<p>One of goals is to make system that has the least variance in handling. We combine mouse inputs with keys
and don't use keycodes whatsoever. Key combinations are supported. Everything is represented with an encoded string:
<pre>[control+]+control</pre>
Any variant should be combinable, even things like mouse movement + key press.
<p>One current limitation of such design is that actions will only be reported in next frame after they
were first declared, creating delay. It's possible to fix it in the future however.
