GUI Window - catch keyboard events

[RyuMaster]

Hi! I have simple GUI system for user registration. The problem is, when user enters name and press some key, like 'u', which is also happens to be global key to open chat message input, it screws up everything. Is there a clean way to make input text field actually 'eat' all the keyboard input?
