Default CM10.2 Touchpad Disable

Hi All, I dusted off my Prime last week and swapped out the HairyBean Rom for the CM10.2 and was pleasantly surprised by the improvements.

However, it appears that one cannot disable the touchpad via the usual shortkey.

This is a deal breaker for me, as I find it impossible to touchtype without my pesky thumbs keep touching the keyboard touchpad.

I have tried covering the pad with various types of tapes and covers, but all to no avail.

I could not post in the development forum (newbie) so have to ask here ... does anyone have any other ideas on solutions. (preferably ones that don't include removing thumbs or similar).

I have read the posts within http://forum.xda-developers.com/show....php?t=2501812, and have found it confirmed that this shortcut feature is missing in CM10.2


Thanks in advance.
