Override default Iron keymappings?

[HippoMan]

I am using Version 52.0.2750.0 (64-bit) of Iron under linux.

Is there any way to change the browser keymappings within Iron? I don't believe this is possible under Chrome, but I'm wondering whether this might be possible under Iron.

I asked the following Stackoverflow question about this same issue under Chrome, but no one has responded to it:
http://stackoverflow.com/questions/3951 ... y-mappings

That post gives a few more details of what i'm trying to do.

Any help concerning how to change Iron keymappings would be greately appreciated.
