Problem with Chdk for Sx40 on shortcut button?

Am having a problem with the shortcut(alt) button on the sx40 to bring up the (alt)script on bottom left of chdk screen. WAS NOT A problem at first now it is. I just tried it again  and no response when hitting shortcut button. What function should the shortcut button be assigned too for proper chdk function. Right now i don"t have it assigned to any function. If you have to have it assigned to the (alt)function how do you do this?   The steps i followed on the sx40 ckdk firmware GM1001(1.0.00) is to insert the sd card bootable one with card locked and the chdk red logo comes up  ;i then toggle the shutter button and the chdk functions come up normally at top of screen  and then i hit the shortcut button,but no response.
Have enabled booting function under miscell. menu.    If i am missing anything let me know!! Thanks for your help!! When chdk is running properly and you can get to the main menu do you have to program it all over again for the functions you set up the previous time.  Is there a way to save the previous functions set up in the chdk menu?

It doesn't matter what you assigned in the canon firmware, chdk sees it before the canon firmware does.

From what I can understand of your description, the most likely cause is either that either the alt button got re-assigned in CHDK, or the shortcut button physically isn't working. On SX40, the alt button can be assigned to "shortcut", "flash" or "video", so you could just try each of those. You can also reset the CHDK configuration by removing any .CFG files from the CHDK directory of your SD card.

To check if the shortcut button is physically working, try assigning something to it in the canon firmware and see if it works. Doing this without loading CHDK (card unlocked) will ensure that CHDK isn't interfering with it.

REYal,yes, the shortcut button does work when i substituted another function to it with the sd card installed in the unlock position. How would i reset the configuration of it by removing the .cfg files from chdk directory of my sd card?     I am a computer stupie here.  And what would this procedure do?  Thanks for yor help!!

Put the card in a card reader, open the CHDK folder, and delete any files with a .cfg extension. Or just format the card and start over.

On the other hand, if the problem happened because the alt key was re-assigned, it would be much simpler just to try the other too possibilities I mentioned earlier...
