As well as

nice idea :)

This is a tricky one. I thought of suggesting this, but realized more harm could be done by my cat walking across the keyboard if this were put into effect. The bigger issue, however, is how the keyboard commands would function while you're entering text into the chat field. They would have to either be disabled while chatting (or they should use a key like "control" in combination with other keypresses -- just don't use ctr-I, -B, or -U). It would also in this case probably be a very good idea to not have the chat field lose focus when it's a player's turn to bet. Lastly, keyboard commands would definitely need to be enabled and disabled through the options menu; the default should be off to not take players by surprise.

should be disabled as default, at least

Acesskeys atributes (ALT-X, ALT-Y, ALT-1, etc) are easy to be implemented and compatible with almost all browsers

use alt-1 alt-2 alt-3 instead of letters (they are used by the browser itself)

I just put them in:

Check/Fold: Alt-1, Check/Call: Alt-2, Bet/Raise: Alt-3

dont see a problem with the way it is now...as the sayin goes...if it aint broke dont fix it..

why the hell are u bring up a post of almost 3 years old, you must be really bored
