Special input fns.

[ayarin0x0]

Like this, also with 'tab' 'shift + tab' '()' '[]' '{}' and so on.

Assign field 'type' to fn.

e.g.

this.type = 'input'
this.name = 'auto-bracket'

When execute fn, it use 'name' as key.
When push into Tracker, it use 'input' as key.
So, the Tracker can merge them as one type naturally and can also save space.
