Sending Keystrokes to browser?

[Wayne Hazle]

I have a checkbox control that for some reason SAHI cannot click for the life of me.  

I am looking at two hack solutions:

- trying to just tab around the browser until that checkbox gets the focus and then hitting SPACE bar to check the box

- having developers put a secret keystroke, CTRL+ALT+SHIFT+F10 that will check the box

will either of these work?  I hear the one issue may be that I cannot simply send keystrokes to the browser
