Basic integration of ace with plugins.
Use some code where I can rename things.
Provide F6 so we can create the rename shortcut as in WebStorm.
Map rename feature, quite quirky yet.
Add a useful standard ACE shortcut.
Use the meta key symbol where we have it.
Write down all todos for the shortcut overlay data layer.
First piece of data returned.
A key combo must be an array.
More explicit naming.
Simple implementation of detecting a key combo.
Detect some registered shortcut.
#Refactor key combo detection.
Second non-matching key shall hide the overlay.
Detect properly (m)any combination of shortcuts.
#Refactor IFs into while.
Simplify even the while to a more functional style.
Fixed the criss-cross bug.
Rename file.
Move todos into other test files.
