i popped the f1 key off my keyboard long ago. :)

there's a couple things I've done, none of which is really perfect.

you can take a knife blade and pop off the physical key. (isn't good to do on laptop keyboards)

you can go into the autocad directory and rename the help file. this way, when you hit f1, you get a little warning box that says the file couldn't be found. this helps only in that you don't have to wait the few seconds for the help file to load.

some keyboards come with bundled software that gives allows you to disable or change the function of certain keys, but I've yet to see one that will let you disable the F1 key while ONLY in autocad.

this thread should help:

thanks for the link. (& thanks to batiment's comment, i got it to work.)

for me it was the F2 key i kept hitting when turing on and off osnaps. text window be damned!

I owned a GE keyboard for a very short time with a superfluous power button right by the esc key. I wanted to hunt down the person whos idea that was and beat them senseless with the keyboard....
