I know how to do it on a Compaq keyboard...
Hold down the left shift, left control, and left alt.
Then tap the left space bar twice and the right space bar once. This will cycle through space/backspace options for each bar. [sig]<p>Doug<br><a href=mailto:dxd_2000@yahoo.com>dxd_2000@yahoo.com</a><br><a href= > </a><br> [/sig]
