Can't send certain control-key sequences

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In Chrome on OS X, type ctrl-a
2.
3.

What is the expected output? What do you see instead?
I would expect the Ctrl-a code sequence to be sent to the wifi keyboard.  
Instead, Chrome seems to interpret it -- probably to mean go to the beginning 
of line.  Same thing with ctrl-e (end of line).  But some control key sequences 
do work, e.g. ctrl-L

I tried Firefox on OS X, and I lose even more control key sequences.  Same with 
Safari


What version of the product are you using? On what operating system?
2.3.5, Android 4.3 on Nexus 7.  Chrome 29 on OS X 1.8.4
